Re: (89 240hatch)
I use NGK
Denso's are good plugs, but pricey. I swear by them for the Toyotas I service (but they're oem plugs). Tomei uses them in their Derive and Genesis engines, but I personally don't. A local guy had the ceramic section of his densos shatter inside his s14 sr and the hardened iridium tip scored his cylinder walls. That's why he doesn't use them. I use NGK since that's the brand I see Nismo using.

After a lot of different plugs I have settled with the NGK. The SR seems to love them
