[CeliKa GT-S]

What are the stock spark plugs on the Celica GT-S and is it worth upgrading the spark plugs to hks.. is their a notice in performance.

 

[WRENCHHEAD]

the stock ones are iridium. switching out to hks would not yield any power gains..

Anyone know a good online dealer of pregapped denso iridiums? Last set I got on ebay.. would rather buy from a "real place"

 

[WRENCHHEAD]

dealership may be the best bet.

 

[Andy00GTS]

I guess so I know they will be expensive there.

Try a local autoparts store. They can sometimes get Denso, or NGK Iridiums will work just as fine. Make sure they don't look it up by application, though. Give them the original plug number.

I think all the Densos comes pregapped to our cars. I bought a generic one on ebay and it was already pre-gapped to .44mm.

 

[Andy00GTS]

Sounds good. I may order 2 sets if these are good with F/I (nx wet 50 shot)
