Fits LS and LT GM Cars, Trucks and SUV’s.

Increased engine efficiency with improved engine combustion. Gains of up to 15hp have been seen with these coils over stock.  Average gain with no other changes is 6 to 8hp on an otherwise stock vehicle. Gains of up to 35hp have been experienced on heavily modified forced induction applications. Powerful enough to support 2000-plus horsepower forced inductions engines yet docile enough for everyday use.
