out the fast lane b*#@!
:
09 mazda 3s
thinking about replacing my stock plugs with some better performance plugs which ones should i go with for the 2.3L (dunno)
 
i dont even know if you have many options besides stock, but Im gonna agree with theman on this one, stock.
 
there's one called ngk, the stock plugs are ok but i was some better ones. does anybody have a loud clunking noise in the front sounds like driver side, if so what is it the dealer can't find it..
 
the stock plugs *are* NGKs

the clunking noise could be a faulty engine mount.... there's a TSB regarding this issue
 
pulled a plug out to look at it not ngk's all's it said was japan, had a little brown on the white part & the part that curves over the spark area was white.i'm gonna get some ngk iridiums to replace the stock plugs.

iridiums are a waste of money... the normal cheapo NGKs work more than good enough
"performance" spark plugs do not add power!

i know plugs do not add power, but i dont like cheapo plugs, want some that will last for a while. whats in your engine?
 
unless your car is boosted or you have like standalone engine management you really shouldnt waste your money on plugs because the aftermarket ones will just cost more and wont give you any benefits
