MadMax Posted July 26, 2009 Report Share Posted July 26, 2009 In the faqs section on the 3rd page under spark plugs 101, they talk about using rx-7 plugs in a starquest with good results. I am wanting to try this for myself but, i have a few worries about the fitment and the difference between leading and trailing plugs. from what i found leading and trailing plugs are part of the rx-7 ignition system to help with emissions. the only plugs i am able to get a hold of locally are the trailing plugs. Any info on this is greatly appreciated. If anyone has a better plug suggestion id like to hear it especially since these are about $25.00 a set.

michael knight Posted July 27, 2009 Report Share Posted July 27, 2009 Order them from Maxdatrix and get the colder ones (trailing I believe) for the FC3s rx7 and you should be good. I think the thread and length are the same and should work. With that said I didn't do it the last time I put plugs in and went w/ some very cold, 9es i believe, I picked up from a local Honda motorcycle shop. If you find a Honda bike dealer service center you should find our plugs. Link to comment Share on other sites More sharing options...

Indiana Posted July 28, 2009 Report Share Posted July 28, 2009 (edited) http://www.jegs.com/i/NGK-Spark-Plugs/739/BUR7EA-11/10002/-1 That's the plug that was in the car when it was new. Its a cross of the popular plug and that plug you are talking about. Those rotary motors didn't want anything sticking out so that's why they are made like they are, different reasons for different parts in different motors but don't use those in this motor there is no rotor moving the fuel mix sideways past a spark plug in a G54B it just mashes the fuel up to the top so that plug is just dumb to use there is too much shrouding around it and if you want to talk about steel in a head that heats up and causes cracks well those rx7 plugs would go on that (bogus bs) list. You want the fuel to burn the fastest possible and purposely putting the spark as far away as possible sort of goes against that. The plug has the tip sticking out for a reason. There's also a reason why some motors have two spark plugs per cylinder too. http://photos-e.ak.fbcdn.net/hphotos-ak-snc1/hs123.snc1/5289_1027208978663_1778479606_56212_606787_n.jpg They are used in many engines, they are forgotten http://www.google.com/search?q=bur7ea-11&a...lient=firefox-a Edited July 28, 2009 by Indiana Link to comment Share on other sites More sharing options...
Scotty Dont Posted July 28, 2009 Report Share Posted July 28, 2009 Im running the br8eq or whatever the late 80s early 90's rx7 plugs basically our stock plug except with three more tips. In my opinon they are not worth the $7 each price tag. Link to comment Share on other sites More sharing options...
