Im getting a Osiris tune done in a few weeks. Whats the best plugs? i've heard The Greddy L7 or the HKS's... Anyone know what works best?

 

I've yet to see a compelling reason not to just go with OEM, NGK PLFR5A-11...unless you're FI.

 

What mods do you have? Unless you have every bolt-on imaginable I would stick with OEM.

 

intake and exhaust. was told i would make better power. thanks for your input

 

Which intake? Almost all intakes for our cars lose power.

 

fujita

 

It's not worth it to get a tune now, in my opinion.

Get a Motordyne plenum spacer and high-flow cats/test pipes/ART pipes. Then get a tune after that.

Also, as fullvietFX mentioned, most aftermarket intakes result in less power on the VQ35DE engine.

 

i want to keep my engine cover, so i dont want to go with the spacer. HFC are towards the bottom of my todo list

 

If you put on the 5/16 spacer you will be able to keep your engine cover. Also your wasting your $ on your tune. Because your going to have to pay for a re-tune when you add hfc or test pipes and spacer at a later date.. Get all your bolt-ons then tune..

 

^ true n i got my berks after my tune damn

 

but i needed it badly so what the heck

 

if you don't take advice when you requested it...

There is no way that you needed a tune yet. You should have bought a plenum spacer and HFC/TP/ART before you thought of a tune.

You should read up more about cars and mods. Plenty of info on here.

 

thanks for all your input, what i ended up doing is 5/16" spacer, intake, dual exhaust and Greddy plugs. and thats all im planning to do on the performance mods.

 

Get HFC or ART pipes dude! Def worth it if you're gonna tune

 

so when are colder spark plugs recommended? only FI? i do have basically every bolt on (except headers) and a tune
