What’s Included?
The Bosch 26A18A package contains two ICON blades:
Bosch ICON 26A
26 inches / approximately 660mm
and:
Bosch ICON 18A
18 inches / approximately 457mm
This package is designed for compatible vehicles using that specific front-windshield blade combination.
Always confirm the vehicle application before ordering.
Bosch ClearMax 365 Wiper Technology
Current Bosch ICON documentation describes the blade as using:
ClearMax 365
wiping technology.
The design combines a soft rubber core with a protective shell intended to help shield the wiping edge from environmental exposure and debris.
Bosch describes the technology as providing:
- Reduced wiping friction
- Quieter operation
- Protection against environmental deterioration
- Consistent wiping performance
- Longer service life
For current Bosch ICON product information:
ClearMax 365 vs. Bosch fx Dual Rubber
Some older Bosch descriptions and current third-party product listings still refer to:
fx dual rubber technology.
Bosch’s current ICON product documentation instead describes its latest wiping technology as:
ClearMax 365.
For a current Pro Street product page, ClearMax 365 is the better terminology to use for this set.
That avoids combining two generations of Bosch marketing language into a single product description.
Premium Beam-Blade Construction
Bosch ICON uses a:
frameless beam design
rather than the exposed articulated metal framework found on conventional windshield wipers.
A beam blade uses an integrated flexible structure designed to distribute pressure along the wiping edge.
Potential advantages include:
- Consistent windshield contact
- Better conformity to curved glass
- Fewer exposed joints
- Improved aerodynamic performance
- Reduced opportunities for snow and ice to accumulate around frame pivots
DynamicFit Tension Spring Arcing
One of the major technologies separating ICON from basic replacement wipers is Bosch’s:
DynamicFit tension spring arcing.
The internal spring structure is designed to follow the curvature of the windshield while maintaining pressure across the wiping edge.
This matters because a windshield is not flat.
Its curvature changes across the sweep of the blade.
Maintaining proper pressure helps reduce:
- Streaking
- Edge lift
- Missed areas
- Skipping
- Uneven wiping
Why Windshield Curvature Matters
A wiper blade must remain in contact with the glass throughout its entire sweep.
If pressure becomes uneven, one portion of the blade may lift away from the windshield.
That can create:
- Water streaks
- Unwiped sections
- Chatter
- Reduced visibility
Bosch’s tension-spring design is intended to adapt the blade to the windshield’s curvature rather than relying on a series of individual articulated pressure points.
Integrated Asymmetric Spoiler
Bosch ICON also incorporates an:
asymmetric aerodynamic spoiler.
The spoiler is designed to use airflow to help maintain downward pressure against the windshield as vehicle speed increases.
This becomes particularly important during highway driving.
Without sufficient aerodynamic control, airflow can contribute to:
wiper lift.
When a blade lifts even slightly away from the windshield, wiping performance can deteriorate.
Designed for Highway-Speed Contact
At higher speeds, air flowing over the hood and windshield places aerodynamic loads on the wiper blades.
Bosch’s integrated spoiler is designed to help keep the blade pressed against the glass.
Potential benefits include:
- Reduced lift
- More consistent wiping
- Better high-speed contact
- Improved rain visibility
That can be particularly useful during highway rainstorms, where both water volume and airflow increase dramatically.
Up to 40% Longer Performance Life
Bosch states that ICON can provide:
up to 40% longer life than other premium wiper blades.
This should be treated as a comparative manufacturer claim rather than a guaranteed service interval.
Actual wiper life depends heavily on:
- Climate
- UV exposure
- Heat
- Snow
- Ice
- Road salt
- Windshield contamination
- Frequency of use
- Parking conditions
No wiper blade lasts forever.
Eventually the sun wins.
26-Inch Bosch ICON 26A
The larger blade in this package is:
Bosch ICON 26A
with a nominal length of:
26 inches / approximately 660mm.
On compatible applications, the longer 26A blade is generally used on the driver side.
Bosch’s current application guidance should always be used to verify the exact vehicle.
18-Inch Bosch ICON 18A
The companion blade is:
Bosch ICON 18A
measuring:
18 inches / approximately 457mm.
This blade is typically used on the passenger side when specified by the vehicle application.
The substantial difference between the 26-inch and 18-inch blade lengths is intentional.
Why Does One Side Use a Much Shorter Blade?
Windshield-wiper sizing depends on more than windshield width.
Engineers must account for:
- Wiper pivot position
- Windshield curvature
- Cowl geometry
- A-pillar clearance
- Blade overlap
- Sweep pattern
That is why a vehicle may legitimately use a 26-inch blade on one side and an 18-inch blade on the other.
Installing a longer passenger blade simply because it appears to fit can cause interference with the other blade or surrounding bodywork.
What Does the “A” Mean on Bosch ICON Blades?
Bosch uses A and B designations to distinguish certain ICON blade applications.
According to Bosch’s application guidance:
The driver-side ICON blade is always an A blade.
Depending on windshield geometry, the passenger-side application may require either an:
A blade
or:
B blade.
The B version incorporates greater curvature for applications that require it.
Therefore:
18A and 18B should not automatically be considered interchangeable simply because both are 18 inches long.
Correct Bosch application data should determine which blade is installed.
26A18A vs. 26A18B
This is an important distinction for online buyers.
A vehicle requiring:
26A + 18A
does not necessarily use:
26A + 18B.
The nominal blade lengths may be identical, but the blade curvature/application can differ.
This is another reason wipers should not be selected solely by inch measurement.
Hook-Style Wiper Arm Compatibility
The Bosch ICON A-series adapter supplied with this package is designed for compatible hook-style wiper arms.
Depending on the application, this includes:
9x3mm hook arms
and:
9x4mm hook arms.
These are common traditional windshield-wiper connections.
Not for Side-Lock, Pinch-Tab or Top-Lock Arms
This package should not be treated as a universal ICON set.
The supplied product information specifically excludes applications requiring:
- Side-lock
- Pinch-tab
- Top-lock
Vehicles using these or other OE-style attachment systems may require Bosch ICON blades carrying an:
OE suffix
instead.
For current Bosch ICON information:
Bosch ICON A-Series vs. OE-Series
The difference is primarily about vehicle connection and application.
Bosch ICON A-Series
Designed primarily for compatible:
hook-style wiper arms
Bosch ICON OE-Series
Designed for compatible factory-style connections such as certain:
- Top-lock
- Pinch-tab
- Side-lock
- Push-button configurations
Buying the correct blade length with the wrong adapter still produces the wrong wiper blade.
Do Not Buy Wipers by Length Alone
This is particularly important with Bosch ICON.
A vehicle using:
26-inch + 18-inch
front wipers does not automatically use:
Bosch 26A + Bosch 18A.
Correct selection also depends on:
- Vehicle year
- Make
- Model
- Wiper-arm connection
- Windshield curvature
- Driver/passenger application
Always use the vehicle fitment checker.
Quick Installation
When installed on a compatible hook-style wiper arm, Bosch ICON installation is straightforward.
The general process is:
- Raise the wiper arm carefully.
- Rotate the existing blade for access.
- Release the old blade from the hook.
- Slide it away from the arm.
- Align the Bosch ICON adapter with the hook.
- Slide the blade into position.
- Verify the adapter locks securely.
- Carefully lower the blade onto the windshield.
Always follow the instructions supplied with the blade.
Protect Your Windshield During Installation
Place a folded towel on the windshield while the blade is removed.
The wiper arm is spring-loaded.
If the bare metal arm slips from your hand and snaps against the windshield, it can potentially chip or crack the glass.
A towel takes about five seconds.
A windshield replacement takes somewhat longer.
Test Both Wipers After Installation
After installing the 26A and 18A:
- Apply windshield washer fluid.
- Run the blades at low speed.
- Confirm complete windshield contact.
- Check for blade interference.
- Increase wiper speed.
- Listen for chatter or unusual noise.
- Verify both adapters remain secure.
The blades should operate smoothly without contacting:
- Each other
- The cowl
- A-pillar trim
- Windshield molding
Clean the Windshield Before Installing New Wipers
A contaminated windshield can make new blades appear defective.
Before installation, remove:
- Road film
- Wax
- Silicone residue
- Bugs
- Tree sap
- Grease
- Dirt
Clean glass helps the wiping edge move smoothly and reduces unnecessary contamination of the new blades.
Signs Your Existing Wipers Need Replacement
Common symptoms include:
- Streaking
- Smearing
- Chatter
- Squeaking
- Skipping
- Torn wiping edges
- Cracking
- Hardened rubber
- Missed windshield sections
Reduced wet-weather visibility is the most important indicator.
Check the Wiper Arms Too
A premium blade cannot compensate for a damaged wiper arm.
Inspect the arms for:
- Corrosion
- Bent metal
- Weak spring pressure
- Damaged hook connections
- Loose mounting hardware
Poor arm pressure can cause streaking even with a brand-new Bosch ICON blade.
Check the Washer System
While servicing the wipers, inspect:
- Washer-fluid level
- Washer pump
- Hoses
- Spray nozzles
- Spray pattern
New wiper blades work best when the washer system can properly loosen and remove road contamination.

All-Weather Performance
Bosch ICON is engineered for year-round use.
That includes conditions such as:
- Heavy rain
- Summer heat
- Cold weather
- Snow
- Highway spray
Its frameless construction also eliminates many exposed articulated joints where snow and ice can accumulate on traditional wipers.
Summer Wiper Care
Heat and UV exposure can damage windshield wipers even when they are rarely used.
Vehicles parked outdoors experience repeated:
- High windshield temperatures
- Sunlight
- UV
- Ozone
Inspect the blades periodically instead of waiting until the first major storm.
Winter Wiper Care
Beam construction can help reduce snow buildup around exposed frame joints, but ICON blades are not ice scrapers.
Before operating frozen wipers:
- Defrost the windshield.
- Remove heavy snow.
- Free the blade from the glass.
- Remove major ice accumulation.
Do not use the wiper motor to break frozen blades loose.
Replace Both Front Wipers Together
The Bosch 26A18A package makes it easy to replace both front blades at the same time.
Both blades experience similar exposure to:
- Heat
- UV
- Rain
- Snow
- Ozone
- Age
Replacing them together can restore consistent wiping performance across the entire windshield.
