I have put a 50 shot wet on my 2002 S2000 want a colder plug than factory ngk's anyone know of any i have a denso # but dont know if its right because i cant find them anywhere the # is either IK24 or 1K24 need help not going to use nitrous till i have the plugs i need.

 

You will want to go about 2 stages colder. The part number you have is incorrect. NGK uses 2 types of part numbers - for example when I had my nitrous integra I used NGK BKR7e but the part number was also under NGK-6097. You need to find the 4 digit part number NGK uses.

Once you find that search NGK-(4 digits) at summit racing online and youll find it.

Anyways for example this is how my BKR7e's showed up on summit (You need different plugs but this will be used for an example)

Hope this helps a bit.

 

Did some quick research for you

The plugs you may be looking for are DENSO IK24, or DENSO IK22

Also may be used are NGK 3330 and NGK 6097

The denso will be preferred as they are iridium and will last longer but are like 6x the price. The NGK's you will want to change about every oil change also as well make sure you check the plugs after spraying at first and every once in awhile to make sure everything is ok.

 

one of my friends told me that was the number for the denso plugs

 

thanks for the info helped alot
