100-340 Cyl. Head Temp.

The AutoMeter 100-340 Cyl. Head Temp. gauge (model 3536) is a precision cylinder head temperature instrument designed for serious engine builders, performance tuners, and mechanics who demand real-time combustion chamber heat monitoring. As an analog electric gauge with a short-sweep needle movement, this 2-5/8 inch diameter instrument displays temperature data from 140 to 340 degrees Fahrenheit, making it essential for optimizing fuel mixtures, detecting detonation risk, and safeguarding engine longevity during break-in, high-load driving, or modified engine operation.

The short-sweep analog design delivers quick, intuitive needle response without digital lag, critical when monitoring transient heat spikes during acceleration or sustained load. Its electric sensing system connects to a cylinder head probe, transmitting precise temperature data to the gauge face with minimal hysteresis. The black dial with white markings ensures high contrast visibility in both daylight and interior cabin environments, while the compact 5.6 x 5.5 x 5.65 inch footprint and lightweight 0.66 lb construction fit seamlessly into modern and classic dashboard installations. AutoMeter's Sport-Comp line emphasizes durability and accuracy—qualities non-negotiable when managing engine heat stress.

Engine enthusiasts installing turbochargers, superchargers, or raising compression ratios depend on cylinder head temperature feedback to prevent knock and premature wear; this gauge provides that visibility. Road racers, drag strip competitors, and street performance builders use 140–340°F monitoring to calibrate ignition timing and boost levels safely. Installation requires standard 1/8 NPT or metric probe hole access at the cylinder head and basic 12V power/ground wiring. Compatible with virtually all gasoline engines—domestic and import, naturally aspirated and forced-induction—the AutoMeter 100-340 Cyl. Head Temp. gauge integrates into existing gauge clusters or standalone panels with universal mounting hardware.
