I have a friend who wants to drop pulley size on his car down to a 3.5. he wants to know which spark plugs to use. I think he would like to stay away from Autolites. Right now he has no mods. He just wants to drop the pulley size.

It will probably end up getting tuned if it has alot of KR (which he is expecting).

You need supporting mods to drop a pulley...why is that so hard to understand? Like said above...have fun blowing it up or knocking like a mofo and bending plugs with chipped pistons. Also, these boosted motors LOVE copper core plugs...so you and your friend obviously have done your research..

Gonna need more than a tune chief.

Can you not give a straight forward answer? Are autolites the ONLY plugs that will be good enough?

Can you NOT drop a pulley and keep the car safe? Why does everyone think that the pulley is the best mod when it clearly isn't. How about this thread for a clear answer. READ IT AND THE LINKS ATTACHED IN IT.

Great. So they will tune out the KR and a stock GTP will beat his ass. This makes perfect sense.

Stock heat range. What ever plug you want.

This man knows wtf is up.Great. So they will tune out the KR and a stock GTP will beat his ass. This makes perfect sense.

if your gonna drop a pulley size why not go big and come down to a 3.2 pulley..go big or go home is my moto. your gonna get the KR tuned out so u will be alllll good..and get bosch platinum 4s... more arcs the better spark

He doesn't understand your joking.
At least, you better be.

Just so you guys know, I DO understand this stuff! I passed on this information to the guy and he is taking it into consideration. Thanks for SOME of the help. I do understand that you guys are just trying to save some hassles in the future. So, thanks for the concern. That part is appreciated!

OOPS! Double post. Sorry!

If you don't like autolites get ngk TR6's. You're really going to need more than a tune to be safe and without kr. I gaurantee you will have kr no matter what tune you run and you will most likely chip all front 3 pistons. For the sake of the owners motor, open up your exhaust before you drop pulley's and mess with plugs. At least a powerlog and dp if not headers. I have headers, a cai, colder plugs an a tune and I see sometimes between 2-3* of kr on a 3.6 on my 04. Granted that's like running a 3.4 on any pre 93 car
03-06-2010
Didn't you mean any pre 2003 car?
03-06-2010
Yup, my bad. That's what I get for typing too fast on my iPhone
