spark plugs

[blaze1]

What kind of spark plugs best suit the gs?

nice, cheap NGK coppers.<P>Get the NGK platniums if you want them to last longer, but the coppers are cheaper in the long run.

I just put on bosch platinum the 2 dollar ones and I definitely got back lost horsepwer, but I also did valve cover gasket and spark plug wires.

The plus 4 are really sweet but they are about 5.00 u.s a piece.

TRY NOT TO USE PLATINUM SPARK PLUGS<BR>I ONCE USED BOSCH PLATINUM 4+ AND THE ENGINE JUST SHUT OFF AT HIGHER RPM AND THE CAR WILL ROLL FREELY TILL STOP.<BR>I AM NOT SURE THE THEORY BEHIND IT BUT I WAS TOLD BY MANY PEOPLE. (ANYBODY COULD EXPLAIN?)<P>I WOULD SAY JUST USE THE NORMAL NGK SPARK PLUGS

There are also 5,6, & 7 heat range plugs in both series. 5 should be for stock cars, 6 for mildly modded cars [and ZE's], and 7 for the guys with forced induction.

Crap, forgot to add that the ZFR's look like they'll make a bit more power, as they'll be closer to the center of the combustion chamber. Haven't picked up any yet, but I'll grab some for the new motor. Probably in 5 heat range if I can get away with no detonation. Hotter = more power [until you get detonation ]

Cold plugs on a stock engine will foul out too quickly.<P> :p

Assuming you don't melt something. Which is why ceramic heads would be so cool. Got 20:1 CR and 50psi?

You want the air that goes in your engine to be as cold as possible but the engine itself (technicly) runs better the hotter it is. That is why the inside of F1 engine bays are covered with gold plates to reflect the heat back to the engine. That is also why they produce 800hp (and other reasons of course
