I have a 86' rx7 n/a, and i need to get spark plugs, NGK's, on there site is askes for Trailing or Leading? what do they mean? and wat is mine?

 

id say search but thats mean

you have 4 spark plugs two leading plugs and two trailing one set goes on the top (leading) and the second pair go on the bottum (tralling)or the other way around i forget but you just need two of each they should be like BURe9q or some number like that just buy two of each and youll be set

or go to pepboys and ask for as set of leading and trailing plugs for your car

 

thanks alot, search is down

 

it is? i just used it

 

one more thing, my local autozone doesnt carry NGK's but my local NAPA does, what do NGK's usually run around cuz i cant find the specific ones on the net and are bosch 4+ plugs better?

 

ONLY put NGK's in your car. Trust me.

And an easy way to remember which ones go where..

Leading=Lower
Trailing=Top



the plugs are BUR9EQ and BUR7EQ

Any Advance Auto Parts should carry them in stock.

Good Luck and feel free to PM me with any questions you may have!

 

Oh and they should cost around $5-$6 each.

get the regular NON-PLATINUM kind.

 

Don't use piston engine plugs in your car unless you want to destroy the engine. Rotaries use special "flat" spark plugs.

 

Hey guys.
I just removed my a/c & p/s...good thing it's roomy, Ok here is the deal. I noticed one of the plugs (left trailing) stick's out than the other 3 is this normal?
Also I noticed all the plugs were leading which I replaced right away with the 2 L and 2T but still couldn't drive the one plug all the way in please advise. I'm new to rotarys but I could tell the previous owner or his mechanic didn't have a clue on what they were doing.
Do you think some damage may be done to the engine by running on 4 leading plugs?

 

Hey guys.
I just removed my a/c & p/s...nice and roomy. Ok here is the deal. I noticed one plug ( left trailing ) does not go all the way in, is this normal?
Also the engine was runnig on 4 leading plugs which I replaced right away for the official 2T & 2L. what a dumb *** previous owner.
Dou you think any damage was done to the engine by running on 4L plugs?
One more thing after replaced the plugs, still couldn't drive that plug all the way in. I'm new to rotarys but I'm learning a lot from you guys in the club. Please advise, Thanks.

 

Are you Sure..I swore to Jesus that the top was leading and lower was trailing

 

Just checked my S5 manual for S&Gs... Top is trailing, bottom is leading.

 

i thought top sparked first .and the botttom sparked a split second later giving an extra boost?

 

In a S5 Trailing is T for top. Leading is L for lower. Easy way to remember. Also, if you have done any mods to your airflow you can run all 9's (trailing) with no harm and an increase in performance. No numbers, but hotter spark on both seems to burn more fuel. My HC almost dropped to legal on the emissions test when I did this.

bosch=**** any plug from them except normal ones are good but like those 4 electrode special ones are ****


but get NGK all the way and they cost about 5-6 bucks

 

NGK 9s are colder than the 7s. NGK is one of the brands that numbers heat ranges backwards.

 

what plug wires do you guy recommnd?
