I would like to know if anyone has tried the Helix Power Tower and their opinion of this product and Motorvations version for an LS1 engine. I inadvertantly installed NKG TR 55 iridium spark plugs instead of the TR 6s'. Will this make much difference for street use? My car is a Trans Am WS 6 and any other performance tips will be appriciated. Thank you,Unsure Arthur.

Re: Induction Sign In

In general (and I'm NOT a performance nut) spark plugs will possibly buy you durability but for real HP most folks alter intake systems and exhaust or if you really have bucks to spend powered intake with a hole thru your hood and bore out intake valves to be of larger size. High compression tricks help but that could require different pistons.

If you drive this car check that it remains street legal where you are with alterations.

This site sells performance parts which I've never checked out but it's worth a click to see what they have.

Are you seeking a little or a lot of change in HP? T
