Which do you perfer in a 04 coupe 6mt n/a motor? Also does anybody know if either set comes pre-gapped?

1. -Double Platinum NKG 6240 PLFR5A-11, for about $10.00 each

2. -IX iridium NKG 4469 LFR5AIX-11 , for about $8.00 each (researching and found these fail and blow up to motor? a ,member off the board said this any input?)

Thanks for your input guys

 

I was told by the tuners at Technosquare to stick w/the OEM platinum plugs BUT go one step colder, i've got a pretty modded NA. they said that the VQ didn't respond to the iridium plugs very well. i was really torn at first BUT the more & more research i do the more i realize it's the truth. Iridium plugs are good just not the BEST for OUR engines. most people who will tell you different are tryin' to sell 'em to ya.

 

hmm do u know the model number of the platinum step colders? my motor is pretty much bone stock but with a jwt pop so i guess i should stick with the regular oem platinums?

 

replace the 5 with a 6...

oh, and good ol' copper plugs are cheaper and conduct better than platinum. but platinum lasts longer. something to consider....
