^ Thanks, I hadn't even noticed that. Sig changed. *sigh, those were the good ol' days. Now my car is back to stock, most of the mods sold to buy a diamond ring and now raising money for a wedding and maybe a house. You're only a kid once (maybe twice if you're lucky), live it up guys!

 

ok, so then, once I get my intake, headers, and exhaust, which would be best for my 05 es? I share it with my wife, but I always drive it hard.

 

^ iridium NGK or just plain stock. I guess you would need better plugs if you would go turbo, high compression, or NO2. Or maybe even playing with timing, or air fuel ratio.
somebody correct me please.

 

i say use some ngk's since that is stock on you guys car

 

I think it's NGK platinums that are stock, not iridium, btw. And that's probably what I will be going back to now that I'm not racing.

 

thanks a lot! since the car only has <4k miles, should I change them early to upgrade? Or I'm thinking it's not that big of a deal... Considering my mods will be coming sloooowly.

 

My first post in a long time... I changed my plugs a couple of months ago to Autolite XP (XP3924 - I'm looking at the box now) and the car just runs unbelievably smoother. I didn't even want these, but they were out of my regular NGKs. I also noticed much better fuel economy with these.

I've always thought fancy spark plugs were a joke, but I think I'm going to use these from now on.

 

If you have less than 4k on that car, don't bother changing them unless you go turbo. The earliest I can imagine you wanting to change those is 15k, and it's not really needed until at least 30k

 

you should get last months issue of Dsport Issue #37 they have a 15 page discusion on the differences and types of spark plugs out there. They even have the companys and what there spark plugs can do for you. Really enlightning. If i had a scanner i would put it up but i dont.

 

I have a 03 oz rally and its completely stock other than exhaust system but was wondering if bosh platinum +4 were any good for this cardoes anyone know?

 

Sweet 8 year bump. Just use whatever the manual recommends. It's a bone stock Lancer, you don't need fancy plugs.
