Will be boosting about 24psi, i was told to get these spark plugs? Is this the correct spark plug?

 

that's what i run with a .024 gap @27psi

platinum.

 

i had them, but ran into ign issues at 28 psi, i had to go to 8's using 2668's in NGK iridium. my gap was .020 how much power you putting down?

 

Get the regular BKR7E instead of the -11, it's got a shorter ground strap and comes gapped a lot closer to the usual FI gaps. Usually .34-.36", the -11 is .44" gap

 

4554 is what i was told to run it's r5671a-8

 

well i'm a couple days away from starting it up for the first time, my friend that has a turbo K24 240sx said to go with those spark plugs. He said to post on here and make sure they were the correct ones to use, or at least what the honda people use for FI. I'm hoping to make 500whp.

the 2668 is what i was told by john from NGK. they seem to work fine.

 

That's what I used, check your plugs after/during the tune, and see if you need to step up to a colder plug. Btw, you can order those NGK's from Advanced Auto Parts if you have those up in MN. I believe those (the BKR7E-11) are the stock plugs for a 2000 ITR.

for 8 heat range you want NGK R5671A-8

 

Sorry to bump a super old thread but i recently tuned a car for someone that apparently referred to this thread when choosing spark plugs for their K24 and went through the tune with copper core BKR7e plugs that were a little to old and needed to be changed before the car would run smoothly above 10psi. I personally always recommend running the Iridium core plugs in the K series (they last much longer for boosted K series and you won't need to gap them down as far as the copper core plugs.) Please note i also run the copper core NGK plugs and don't have a problem with them BUT if you don't want to worry about changing your plugs/spark blow out as often i would highly recommend Iridium core NGK plugs over the copper core versions. Here is a little article that breaks down the K24 NGK spark plugs to help ensure the correct heat range plug for your particular engine build/power level. Only thing i would add i don't see in the article is be sure to check piston clearance on any high compression NA build, I once had to run a rotary engine style NGK plug (electrode does not protrude past threads for a super high compression K20.

Hope this helps others that windup here while researching their build!
