Great price! Should go fast.

I'm assuming this is for a complete set (6)?

Will it increase HP?

What he said? I've always wondered why people changed to these after getting boosted??

Correct a set of 6

It won't make more HP whether ur N/A or F.I. The reason why most F.I. guys use these plugs or other named brand plugs like HKS are due to the plugs heat range. The GTR plugs ignition and timing of the tips run cooler than the stock spark plugs that come with the Z. By having good and cooler igniting plug u decrease the chances of detonation, pre-ignition, or power loss. This is needed especially when ur going F.I. as u also increase ur chances of detonation, or pre-igniton. These aren't needed for N/A applications. There are other brands of plugs like the HKS plugs that u can use...but the GTR plugs are more affordable. The price that vil9j is offering is a great deal. These plugs usually run $25 a plug or more.
