What does increasing spark plug gap do?

What does increasing spark plug gap do?

The larger the gap, the more voltage is needed to jump the gap. Most experienced tuners know that increasing the gap size increases the spark area exposed to the air-fuel mixture, which maximizes burn efficiency. For this reason, most racers add high-energy ignition systems.

Will wrong spark plug gap affect performance?

An incorrect electrode gap may affect engine performance as the spark magnitude may be insufficient to ensure complete combustion of the air-fuel mixture. If you drive your car normally and tune the engine regularly, you can increase the spark plug gap by about 0.010″ for better performance and better fuel economy.

How much horsepower do air intakes add?

When upgrading your air intake, truck owners can expect an increase of between 5 and 15 horsepower, though this number can be higher or lower depending on your make, model, engine size, and type of intake. This change can be credited to several factors, including the location of the upgraded air intake.

Do K&N drop in filters increase horsepower?

These filters are designed to boost horsepower and torque. That is because allowing more air into the engine tells the ECU to inject more fuel. This gives you a more complete and potent fuel burn. Test results have proven that these oiled cotton filters provide up to 50% more air.

How much horsepower does a K&N air filter add?

He finds that on the dyno, the aftermarket filters do in fact make more than the OEM unit, with the most gains produced by the K&N filter (around four horsepower and five lb. -ft. of torque, or around 2.6 percent and 3.7 percent, respectively).

How much horsepower does an AEM intake add?

The average of two runs with the AEM intake produced a best of 163.31 at the wheels. Doing some quick third grade math (okay, it was a calculator), that’s a gain of 4.4 horsepower. The warmer weather was certainly a factor, making the real gain closer to 7 or 8 horsepower if temps had stayed in the 50s.
