Do we need to increase the gap when installing the MSD blasters? I think I heard somewhere that we are supposed to due to bugger spark. I know the motorcraft spark plugs are "non-adjustable" so I wasnt sure like if we are supposed to increase the gap or not or get a plug with adjustable gaps.

Diabolical!

The motorcraft plugs are adjustable, you just need a special tool to do it. However, you don't need to change your gap just for coil-ons. Word to the wise: don't ever get rid of your stock coils.

I know im not but the msd were on sale and from what i hear theyre the only ones worth getting esp if ur turning extra rpm

Unless you're FI or stroked and bored, I beg to differ.

Thanks, I installed my msd blasters and plugs, at 35k miles my plugs were SHOT. I have the one piece plugs too. I dont know if it was the new plugs or the blasters but wow what a difference. I could actually feel it. Stupid NJ gas crisis
