I would like to know what type of spark plug would be recommended for a 01' CL-S.. Is the NGK Iridiums good?.. i have it on my last car it didn't perform any better.. any recommendations?.. if anything i'll get the NGK Iridiums..

 

It will barely help on a n/a car, but it will definitely last a really long time. You may get better starts and very slightly better gas mileage, but that's it.

 

I have Denso IK20 and haven't noticed a difference.

 

i have them in mine. no difference.

 

what's the recommended part # of the irridiums anyway? (supposed to be a colder plug or something...)

 

NGK Iridium IX
ZFR6FIX-11

 

whats the model number for OEM spark plugs for Type S?

 

I just bought a set of these iridiums from www.spakplugs.com

cost seems to high for the Double Platinum


NGK IX iridium 2477 ZFR5FIX-11 0.044 $6.95

stock NGK Double Platinum 4363 PZFR5F-11 0.044 $11.71

 

how much did you pay for shipping & handling?
www.rockauto.com also has them for a slightly lower price, but they only sell them in packs of 4....

 

I think it was $8,, just call the 800 number on the web page they will tell you exactly to ship where you live.
