Ok im going to change the spark plugs..what number should i use i.e. 9, 10? and i know to use ngk but what size gap should i use? thanks

you cant gap plugs for rx7's



if you ahve a stock car go with 7's and 9's.



part number

bur7eqp for trailing

bur9eqp for leading

walk up to the guy behind the counter and say "i need 4 sparkplugs for a mazda rx7 [insert year], 2 leading 2 trailing." They will then tell you what sparkplugs they have for that model/year of car. Choose from those. https://www.nopistons.com/forums/pub...IR#>/smile.png

ok this is dumb but uh what ones are trailing and what ones are leading?



should i ask the guy if he has titanium valves also?

oh yeah....... you might wanna go straigth to a mazda dealer..... cuz you might have a hard time finding them in your local car parts stores

leading are the spark plugs towards the bottom of the car, and trailing are the ones on top.

thanks

They come all together in a box from the dealer, with a picture of where they go even. https://www.nopistons.com/forums/pub...IR#>/smile.png

oh yeah......... one more advice... replace them one at a time.... you dont wanna accidentally switch wires and blow the engine

yeah dont need a blow engine the first weekend we get it

also the sparks plugs will have a "T" for trailing and "L" for leading. as has been said, "L" also stands for lower.



i can find them in stock at my local advanced auto. never in strauss and i dont recall if they had them in auto zone. never tried pep boys.



also i hear its better to do them from underneath the car. i changed them from above. if your doing so, id start with the front trailing as its the hardest to get to. at least it was for me.



hope that helps.

napa carries the platinum

We definately carry them at advanced auto. I work there https://www.nopistons.com/forums/pub...IR#>/bigok.gif

autozone does not carry them, they do not sell any NGK plugs

O'reillys has them. 5 bucks a plug.

wait do you have an FD yet?

its only like a 6 page long thread on her acquiring one...

like i said...... mazda dealer..... since everyone is whoring... i might as well too

get spitfire quad spark 7s they ahve four yes four sparks at a time there bloody dear tho

would you mind posting pictures of the sparkplug you are describing? cuz typical rx7 spark plugs has 4 contacts for spark

i got it yesterday..im trying to get pics of it. im probably going on saturday to get some plugs. ill just get NGK from a mazda dealer

Like I said in the other post, " I call BS until I see pics".

i got all 9's for my car mike forced me to nothing wrong with that right i still havent changed em

I think I keep my local Advance Auto store in buisness just from buying plugs. https://www.nopistons.com/forums/pub...IR#>/wacko.png





Some people recommend all 9s for the amount of mods you have.
