which spark plugs???

[turbolude]

this weekend im going to be running a turbo on my f22 stock block.. im going to be running 8psi so i was wondering what type of spark plugs do i runn on this setup?? and should i install it this weekend too or do i install it right b4 the tune??

I would install some sone ngk's bkr7e for your set-up and I would install them as soon as you get them. You might want to gap them a little lower than what is recommended because you're boosted

how do yu gapp them?

where do i go to get this done?? and can i jus buy one tht already has the gap tht i need?

So...let me get this right. You're boosting your car, but you don't even know how to gap a spark plug? This is going to end well.

I think you need to do a little more research on turbo, spark plugs, and how they are related.

spark plugs are incredibly important to an engine, too cold of a spark and it wont ignite the mixture to hot and it could cause severe damage to your block (melt it into a puddle) also read up on the dwell time might need to change it also

What about E3's are they any good for a turbo set up? I've heard really good things about them from some muscle guys.

You don't need fancy plugs. They do nothing. NGKs made with the proper material, with the proper gap for the application... that's all anyone needs.

I was under the impression that with a turbo you needed different plugs from stock? Not true? Just magazine fiction?

when you added turbo you changed the pressure inside the cylinder so you would need a hotter spark to make up for the higher compression so yeah you do need to change them but doesn't really matter if they are e3 or whatever as deev said its just a different material which it is made from, what you need to check on the spark plug is the parks intensity, and its ability to dissipate heat

Yes, you need plugs with a different gap, and quite possibly a different material (such as platinum or irridium). However, you do NOT need to get these fancy "performance" plugs that make all sorts of horsepower promises.

As I said to the OP... perhaps you should learn what is actually involved in making a turbo system function correctly and reliably, rather than relying on the words of other amateurs, or magazine claims.

Actually, forced induction generally needs a colder plug.

The hot/cold rating on a spark plug has nothing to do with how hot the spark is. It has everything to do with how large the ground strap/exposed spark plug is. Hotter plug will be smaller, so the body of the plug gets hotter to burn off deposits. Colder plug will be larger as to absorb more heat before getting hot. Too hot of a plug in a turbo motor will cause a hot spot and the potential for pre-ignition or detonation. Too cold of a plug will foul up over time, since it doesn't get hot enough to burn off deposits.
