spark plugs

[mbw1406]

Whats the best type of spark plugs and plug leads for the twin turbo, also would upgrading to a k and n cone filter be worth the money, does it actually improve performance or does it just increase the engine sound???? Would a aftermarket panel filter be better.

Personally I am a firm believer that a spark is a spark. Performance plugs, multi electrodes and different materials all produce a single spark of the same duration. Admittedly some plugs last longer than other and thinner electrodes are better than thicker ones but I doubt a driver will notice much of a difference.

If you combine an induction kit with a cold air feed you should see a power gain through the mid to high end of the rev range and it will sound great. Have you done anything to improve the exhaust?
