Auto Meter 2259 Electric Cylinder Head Temperature Sender

Why Cylinder Head Temperature Matters

Cylinder head temp (CHT) tells you what’s happening where it counts:

• Combustion heat levels
• Engine stress under load
• Early signs of overheating

Unlike coolant temp, CHT reacts faster and gives a more direct picture of engine conditions.

Too hot?

• Detonation risk
• Warped components
• Engine damage

Too cold?

• Inefficient combustion

This sender gives your gauge the data needed to catch issues early.

Essential for Air-Cooled & Performance Engines

This sender is especially valuable for:

• Air-cooled engines (VW, Porsche, etc.)
• High-performance builds
• Turbocharged applications
• Track-driven vehicles

Anywhere temperature control is critical.

Fast Response to Temperature Changes

Mounted at the cylinder head, this sender:

• Reacts quickly to load and combustion changes
• Detects heat spikes early
• Helps prevent overheating damage

Because head temps rise fast when things go wrong.

1/8in. NPT Replacement for Brief Sweep Electrical Cylinder Head Temperature gauges. This sender most effective works with 1995 and later gauges. This sending unit may also be used for brief sweep Electrical water, oil, and trans temperature gauges the place sending unit clearance is a matter.

Key Features & Functions

Direct Cylinder Head Temperature Measurement

The 2259 sender mounts to monitor cylinder head heat, providing:

• Faster response than coolant-based readings
• More accurate combustion-related temperature data
• Critical insight for tuning and performance

Because coolant temp doesn’t always tell the whole story.

Electric Signal Output

Designed for use with electric CHT gauges, this sender:

• Converts heat into a precise electrical signal
• Provides stable, consistent readings
• Eliminates the need for mechanical temperature lines

Clean install, reliable data.
