Hey guys,

I recently got into another 240 and I’m looking into doing a tune up. Right now, I’m looking at spark plugs. I noticed on that there doesn’t seem to be any listings for NGK Iridum spark plugs for the KA24E. They’re available for the KA24DE, but why not the E?

I did take note that some people on other forums are using NGK Iridiums in their E, but how would I go about knowing which plug I’m supposed to be looking for?

Thanks

I think that almost everything for the SOHC and DOHC are about the same, when it comes to exhausts, headers, intakes, spark plugs, etc. A couple of things are different. But yea, most are and should be compatible. Also, its great to see that your getting back into the scene! Dedication at its max!

Hey,

Thanks for the reply.

I was reading on 240SXForums that the DE uses slightly longer or shorter spark plugs, any info on that?
