What’s Included?
The BOSCH 24A18A package includes:
- 1 Bosch ICON 24A blade
- 1 Bosch ICON 18A blade
This combination is intended to replace both front windshield wipers on vehicles requiring this exact Bosch pairing.
Why Bosch ICON Beam Wipers?
Bosch ICON is a premium beam-style wiper line.
Unlike older conventional wipers that use an exposed framework with multiple pressure points, the ICON design uses an integrated beam structure engineered to conform to windshield curvature.
Bosch describes the design as distributing more uniform pressure along the blade for consistent all-season wiping.
That can help reduce:
- Streaking
- Missed windshield areas
- Blade chatter
- Uneven contact
- High-speed blade lift
Bosch ICON Rubber Technology
Bosch advertises its current ICON line with ClearMax 365 rubber technology and states that it provides up to 40% longer performance life compared with other premium blades in Bosch testing. Bosch also says the rubber has demonstrated strong resistance to cracking from ozone exposure.
That matters because windshield-wiper rubber is constantly exposed to:
- UV radiation
- Heat
- Ozone
- Freezing temperatures
- Rain
- Road grime
- Washer-fluid chemicals
These conditions gradually harden and degrade ordinary wiping edges.
Beam Design for Curved Windshields
Modern windshields are rarely flat.
The Bosch ICON beam structure is designed to flex across the curve of the glass rather than relying on a traditional articulated metal frame.
Bosch’s previous ICON documentation describes its A- and B-series blades as using tension-spring arcing technology to create a shape matched to windshield curvature.
This is also why buying replacement wipers strictly by length can be a mistake.
What Does the “A” Mean in 24A and 18A?
The A suffix matters.
Bosch explains that ICON blades use different curvature profiles depending on application.
According to Bosch:
- The driver side normally uses an A-series ICON blade.
- The passenger side may use either an A-series or B-series blade depending on windshield curvature.
- B-series blades use greater curvature for certain passenger-side applications.
This bundle contains:
24A + 18A
not simply generic 24-inch and 18-inch blades.
That distinction matters.
Don’t Replace 18A With 18B Just Because the Length Matches
An 18A and 18B may both measure approximately 18 inches, but Bosch designed them with different curvature characteristics.
Using the wrong profile can lead to:
- Poor edge contact
- Missed areas
- Streaking
- Chatter
Always follow the vehicle-specific Bosch application listing.
Aerodynamic Spoiler Design
The ICON blade incorporates an asymmetric aerodynamic spoiler.
Bosch states that this design helps distribute downward force along the blade and hold it against the windshield.
That becomes increasingly important at highway speeds.
Air flowing over a vehicle can create lift on poorly designed wipers.
A blade that wipes perfectly at 25 mph but floats away from the windshield at 70 mph is not especially useful during a freeway downpour.
Designed for All-Season Driving
Beam-style wipers are particularly useful when weather becomes unpredictable.
Potential benefits include improved performance in:
- Heavy rain
- Road spray
- Light snow
- Freezing weather
- Hot summer conditions
The smooth beam construction also gives snow and ice fewer exposed frame joints to collect around compared with traditional framed blades.
Quick Hook-Arm Installation
The supplied 24A and 18A ICON blades are designed around compatible hook-style wiper arms.
The product information identifies compatibility with common:
- 9x3mm hook arms
- 9x4mm hook arms
when specified for the application.
Installation typically requires:
- Raise the wiper arm.
- Rotate the old blade away from the arm.
- Release the existing blade.
- Slide the Bosch ICON adapter onto the hook.
- Confirm it locks securely.
- Carefully lower the arm back onto the windshield.
Never allow a bare metal wiper arm to snap against the glass.
Windshields remain surprisingly intolerant of that experiment.
Not for Every Wiper-Arm Style
The A-series blades in this bundle should not automatically be assumed compatible with:
- Side-lock arms
- Pinch-tab arms
- Top-lock arms
- Specialized OE connections
Bosch offers other ICON connection versions, including OE-suffix blades, for many non-hook applications. Bosch’s current ICON program includes OE Multi-Clip solutions for several OE-style connections.
If your vehicle uses a non-hook attachment, verify the exact Bosch part number before ordering.
Why Wiper Length Alone Is Not Enough
A common mistake is seeing:
24-inch driver / 18-inch passenger
and assuming any 24/18 combination will fit.
That’s not always true.
Correct fitment can depend on:
- Year
- Make
- Model
- Body style
- Wiper-arm attachment
- Windshield curvature
- Blade-specific A/B/OE design
Bosch itself recommends using its application catalog or fitment lookup to determine the exact blade numbers.
Verify Your Vehicle Before Ordering
Always enter your:
Year → Make → Model
into the vehicle fitment checker before purchasing.
Our Shop Car Parts by Vehicle the Smart Way guide explains why exact vehicle matching is important even with seemingly simple maintenance products.
Two cars can use the same blade lengths and still require different adapters or blade profiles.
Signs Your Current Wipers Need Replacement
Even premium windshield wipers eventually wear out.
Common symptoms include:
- Streaking
- Hazy windshield areas
- Chattering
- Skipping
- Squeaking
- Missed sections
- Torn rubber
- Hardened wiping edges
If your current wipers are leaving a blurred band directly in your line of sight, replacement should move fairly high on the maintenance list.
Clean the Windshield Before Blaming the Wipers
Poor wiping is not always caused by worn blades.
Windshields collect:
- Road film
- Wax residue
- Tree sap
- Bug residue
- Oil
- Silicone contamination
- Dirt
Clean the glass thoroughly before diagnosing new wiper blades as defective.
Also wipe the blade edge with a clean damp cloth.
If streaking remains after cleaning, blade replacement may be appropriate.
Beam vs. Conventional Wiper Blades
Conventional Wipers
Traditional wipers use an exposed metal frame with several pressure points.
Advantages include:
- Low cost
- Wide availability
- Simple construction
Beam Wipers
Beam blades use an integrated curved structure.
Potential advantages include:
- More uniform windshield contact
- Cleaner appearance
- Fewer exposed joints
- Better aerodynamic behavior
- Better adaptation to curved modern windshields
For more detail, see our Best Windshield Wiper Blades for Clearer Drives guide.
Why Windshield Curvature Matters
The farther a wiper travels across curved glass, the more its structure has to adapt.
If the blade does not conform correctly, the wiping edge may lift at:
- The center
- The outer edge
- The passenger-side corner
That’s one reason Bosch uses different curvature profiles within the ICON line.
A blade isn’t simply a rubber strip with an inch measurement stamped on the package.
Highway-Speed Wiping
The ICON spoiler is intended to help maintain contact at speed.
This matters when driving through:
- Heavy freeway rain
- Truck spray
- Crosswinds
- Storm conditions
Consistent pressure helps prevent sections of the blade from lifting away from the windshield.
That helps maintain a cleaner viewing area when visibility is already poor.
Hot-Climate Performance
Wiper blades can degrade even when they are barely used.
Heat and ozone attack rubber while a vehicle sits parked.
That makes rubber durability especially relevant in hot climates where vehicles spend hours sitting in direct sunlight.
Bosch’s durability claims focus in part on resistance to ozone deterioration and long-term rubber cracking.
Cold-Weather Performance
Beam blades also eliminate much of the exposed joint structure found on conventional wipers.
That can reduce places where:
- Ice
- Snow
- Slush
can accumulate.
Wipers still need to be freed from the windshield before operation when frozen in place.
Do not use the wiper motor as an automatic ice scraper.
Replace Both Front Blades Together
This Bosch bundle makes it convenient to replace both front blades at the same time.
That can help maintain more consistent wiping performance across the windshield.
If one front blade has degraded significantly from age and weather exposure, the other usually experienced the same environment.
Inspect the Wiper Arms During Installation
When changing blades, inspect the arms as well.
Look for:
- Bent arms
- Corrosion
- Weak spring pressure
- Damaged hooks
- Loose mounting hardware
Even a premium blade cannot wipe correctly if the wiper arm cannot maintain adequate pressure against the glass.
Protect Your Windshield During Installation
Place a towel over the windshield while replacing the blades.
If the raised metal arm accidentally falls, the towel provides an extra layer of protection.
When installation is complete, gently place the blade against the glass rather than letting the arm spring down.
Test Before Driving
After installation:
- Wet the windshield with washer fluid.
- Run the wipers at low speed.
- Confirm both blades sweep normally.
- Check that they do not contact each other.
- Check for trim interference.
- Verify the adapters remain locked.
Then test at higher wiper speed.
