hey guys. im getting ready to the the 60k tune up and i saw these e3 spark plugs. i was wondering if anyone has used them in their Rx7, and if they did, what did you notice? are they any good?

Thanks in advance guys!

 

Nooooo.... Do not run anything but NGK's meant for our engines. I doubt those E3 plugs have the specific tip for a rotary engine and worst case the tip of the apex seal will catch the spark plug and there goes your engine.

If this were a piston engine I would say knock yourself out. That or if you can verify that the tip of the spark plug is the same as the ones used in our engines.

 

I've only run NGK's too.. but damn they are expensive (in terms of plugs)..

 

E3 does not make plugs for Rotary. in fact most Spark Plug manufactures CANNOT make plugs for rotary because its much harder to do, and it cost a lot more + market is small

Best plug came from NGK. in fact most aftermarket spark plugs are just re-branded NGK with the company's own setting (like colder plugs from HKS)

 

i figured they didnt make the proper tip. What kind or NGK's should i use?

 

Look them up on any auto parts web site. There is only one type of plug with a leading and trailing plug...you'll need a pair of each.
