this is my first tune up on my current lude. oem is ngk platinum lasers and they are expensive as hell. has anyone put in any other ngks? the list of compatible plugs is fairly long, but the price difference is huge. my cost on the lasers is 11 bucks and the other ngks are like 2-4 bucks apiece. if i buy the cheaper ones am i going to run like shit or will i just have to replace them alot sooner?

 

ngk coppers

 

NGK coppers are cheaper but only because they must be replaced more often. Platinum is good because they can go for 60k miles plus without replacement, but copper plugs should be replaced at least every 10k miles.

 

are you at a 105k the platinums only have to be replaced every 105k if you don't believe me check your manual.i always use the oem recommended plugs.

 

always buy ngk's, i bought borsh once and they were no good. i returned them to kragens and they did credit that and ordered the ngk's for me. for that 50 bucks, its worth your money. and yes, replacement at 105k if yours are platinum (97+ ludes)

 

I installed the NGK Iridium's into mine (yeah, I know they're expensive but damn I was curious). They're OK, but not worth the $50/set IMO. Just run with the platinum plugs.

 

I used the regular NGK's for $7 for 4, tell you the truth i cant tell any down grade in performance. If anything it fells better because i know the previous owners were running on the original plugs and didnt swap them out. And paying $12 a plug is crazy even though they last longer thats all the difference between the V power NGK plugs and the Platinum ones. Performance wise no difference check it out... i got this from the NGK website


Platinum

Platinum is a precious metal used by NGK in its long life and/or performance spark plugs. This is because of platinums high melting point which makes it useful in two ways. On a long life spark plugs a thin wafer of platinum is bonded at the firing point to the center electrode (and possibly ground electrode) solely so they dont wear as fast as a traditional plug. On a fine wire performance plug, the very tip of the center electrode is made of platinum so that the fine wire tip will last longer. Do not be fooled, all platinum plugs are not created equal, Platinum is a very expensive precious metal, a $2 platinum spark plug will not have much platinum in it, and therefore will not last as long as a $12 platinum spark plug. NGK platinum plugs contain the highest platinum content in the industry. Some platinum plugs have only the center electrode tipped with platinum, while others have both the center and ground electrodes platinum tipped. (By the way, it is still not suggested that platinum plugs be used on vehicles with nitrous injection. Thus far, there has been no problems reported regarding using iridium plugs with nitrous.)
