I’ve seen so many spark plugs on-line that the sheer number available for my ’02 S2K is overwhelming. I am by no means an expert and I wanted to hear form those that know and/or have gone through the same thing I am experiencing as to what is the best spark plug out there for our vehicles. Thank you for your reply.

 

OEM. Just go to the dealership and pick them up. there pretty expensive.
DON'T buy ones that have 2 or 3 electrodes. waist of money. make sure you torque them down to spec. theres a FAQ in the under the hood post thats very good.

 

I just put in the NGK Iridiums in my 02 s2k, I believe the code is BKR7EVIX-11, gapped to .043". I plan on replacing them every 2 years. The stock ones were in horrible condition after 55,000 miles, hate to think what they would look like after 100,000. The car runs super smooth with the new plugs. I'd recommend them, same manufacturer as stock, same heat range, better firing tip design IMO. They aren't cheap but should be lesss expensive than the dealer supplied ones.

 

Just bought some a couple weeks ago, installed them last week.

OEM NGK PFR7G-11S for $48.95 + free shipping on eBay. Seller shipped them out very quickly.

ngk iridiums are about 10 bucks each cost about the same as oem then.

 

i bought NGK iridiums also, car seems fine and slight MPG increase but plugs taken out (at 76K miles) looked very worn so that could have just caused the increase in MPG. ordered mine of amazon.com for a good price (in the 40s). you can read the SAE technical papers done by denso when they developed the iridium plugs and come to your own conclusion (if you search for ngk iridiums or spark plugs on this site), you will find a link to the SAE papers.

 

ngk copper & change them every 2 oil changes

 

this is not your typical honda, NGK made a specified plug for our car and the copper plug is not cutting it.

i love those on my turbo'ed honda in the pass but don't use the copper plug in your s

 

I used them with no problem before & after turbo... personal preference i suppose

 

I'm surprised nobody has given the Denso IK24 any love! If you rarely do very short drives (like to the corner store and back), and don't live in an extremely cold climate, then I think a colder plug is preferrable. I would have tried an NGK plug if they had one available in an 8 heat range, but I couldn't find one.
