Ok guys, sorry for the extra posts... but just trying to get things in order.

I think i need to put some fresh plugs in my car. Simply because i did not do it when i did my swap, so they are probaly still stock with who knows how many miles on them.

I really dont know much about plugs. I did a little search but didnt come up with much i understood. LOL.... Yes, i can do a K swap, but NO, i dont know shit about plugs. I dont know if mine are bad, but i pulled then when they were cold and they were looking pretty darn black. Let them idle for about 15 mins and they lighten up, but looked like their might be small depostits on them (not that i know what deposits look like..lol) So, i think they may be fouled, and being that im still tunning my A/F id like to get a couple fresh sets to use to make sure im getting acurate A/F readings.

So, basicaly im looking for some affordable plugs. Nothing fancy. I head some basic NGK's may be the way to go, or maybe just stock??? Can someone set me up with a recomendation and some part numbers?

Also, what is the stock gap? And is stock gap good or are you guys getting better results with a larger gap? And whats the propper gapping procedure???

Sorry for all the questions. Just want to learn a little and get setup right


Thanks all

---Joe

Re: Which spark plugs????

If this is a DD and you are NA then the only plugs that will run right are Iridium plugs, my choice would be Denso IK22's 8$ a pop at AutoZone.

Never ever try to gap Iridium plugs, any contact with metal will remove the Iridium. They come pregapped.

Re: Which spark plugs????

I am NA and this is not a daily driver. She gets driven to the track once every week or two, and may once in awhile take some light road trips.. thats about it .

Re: Which spark plugs????

The Iridium plugs last a hell of alot longer than conventional plugs, so in the end, the costs end up being the same for a daily driver.

I tried a set of platinums and immediately noticed drivability issues and within 2k miles started misfiring and stumbling.

I have "heard" of guys running copper plugs at the track, but they were very short lived.

IK22's FTMFW!

Would recommend them to any modded K! Maybe unless they're turboed, then go one step colder.

Re: Which spark plugs????

why is it that copper plugs dont work well with this motor???

the IK22'S..... is there a part number??? or is ik22 the park number???

$8 a pop is still a good amount for plugs... anywhere i can get these, or the oem ones any cheaper????

Do the IK22 have integral resistors built into them?

Re: Which spark plugs????

How would the Denso's recommended IK20 for the rsx be any difference then the IK22?

FWIW, part number of IK22 is PK22PR-L11.

IK22's are one step colder than the IK20's. A colder spark help will against pinging/knocking.

IK22's are the stock heat range for the K20A2, the K20A3 (base RSX) uses the IK20 plug.

I just went to denso web site and IK22 is stock heat range for k20a2, I bet that bastard gave me some for base model, I know I told him type S, just a reminder of making sure people at auto zone get your shit right.
