SLP Fan Control Switch, 1993-02 V-6/V-8 Camaro/Firebird.

Fan-Control Switch, 1993-02 V6/V8 Camaro/Firebird Today's engines are built to run hotter-for reasons unrelated to performance! The higher temperatures mean less aggressive spark lead timing and lower advance curves or knock sensors, which retard timing at high engine loads to prevent detonation. If you run it hot, performance goes downhill. Stock cooling fans are set to activate at 215º F, too hot for high performance use. The easiest ways to optimize the performance of your car is to run it at a lower operating temperature. To combat high-operating temperatures, SLP Performance Parts developed an easy-to-install Fan Control Switch. This switch allows you to turn you car's electric coolant fans on manually, yet still retain stock fan operation. So, if you're sitting in traffic or at the track waiting in the staging lanes between rounds, you can click on your fans early to keep your engine operating efficiently and producing as much power as possible. Lowering your engine's operating temperature will not only increase performance, it will add reliability and longer engine life, by decreasing the stress cause by heat fatigue. All necessary hardware and instructions for an easy plug-in installation are included with this part.
