What would be the best plugs for fully built ls/vtec boosted? Car is on 11 psi if that makes a difference.......



Also, is it bad to go from full synthetic to synthetic blen oil??

 

Full synthetic and synthetic are the same thing. Some brands just say "Full". And you want to use a colder degree plug.

 

Ngk BKR5E is the one you need i believe

 

Are 8s colder than 11s? and i mean switching from full synthetic to conventional 10 30

 

It isn't advised that you switch from conventional to synthetic and visa versa.

Check out this page for numbers/heat range

Why do people cheap out on oil? Run synthetic, always. This isn't a tercel man

 

Way, way back, before any of you were born, synthetic oils developed a reputation for drying-out seals. This reputation is no longer valid, if it ever was.

Nowadays, you can safely use whichever oil you want--mineral or synthetic or a blend--so long as it meets the automaker's specifications. And you can safely swap between one type and the other as you wish.

I will say, though, I am mightily impressed with how sparkly-clean synthetic (Mobil 1) keeps my engine, and I have no plans to switch back.

 

^^ that rumor is probably true of running conventional for a long time then switching to synthetic

 

I stayed with synthetic lol

 

its boosted on 11 psi... wow means nothing
