Searching proved futile.

Does anyone know which is the correct sparkplug for a 1972 2.4 "T" motor?

Bosch says W5DP0, but that doesn't sound right...

Also heard about W4CS, but that's listed as a "racing" plug.

Well, it depends a little. Is the 2.4 a carb'd or CIS motor?

It has MFI.

The W5DP0 is right for your engine, BP8ES was the alternate (read "cheap") plug when the engine was new, but BP7ES will probably work well with today's fuel. The W5DP0 is major bux, the NGKs aren't. Be prepared for poor transition performance, and there's NOTHING you can do about it. It was that way when they were new, and wear doesn't help. The fix is to change the throttle bodies, have Gus make the pump into an E, and change the cams. Enjoy! The Cap'n

Thanks. I'm swapping to PMO's soon.
