Guys, what NGK iridium plugs would you recomend for the FD??

Spec:

5Zigen cat back
Custom stainless intake pipes
K&N filter (with cold feed)
Massive blits FM intercooler (set in Vmount position)
Greddy intake elbow
Walbro 255 pump
Double throttle removed
0.9 bar boost on stock sequential twins (going to be custom before too long )
Std injectors @ the mo (going to be putting a second set of secondries in so 6 injectors in total)

Any sujestions as I can get them through work at a good price

Just been trying to purchase some NGK BUR10EQP plugs for the trailing side!

Apparently NGK do not do these anymore?


I would recommend a 10 rated plug in the trailing side and the NGK BUR9EQP in the leading! More so if your attending track and quarter mile events

do NOT use iridiums. they have welded electrodes which will break off in a rotary engine alot easier than in a piston motor.
the bur plugs are fine as are the egv plugs, egvs abit better for a hotted up motor.

That is only the Denso plugs
 
The NGK plugs are fine!
 
Ive run them in my engines without fail and a lot harder than most would.

Hi, its Ben from lindopmotorsport we recomend using 9eqp\'s on std rebuilds and race plugs in modified engine\'s, we can supply both if needed, nice and cheap. Race plugs are £24 each, std plugs are £8.27 each. Give us a call if you need them and i can get them posted out to you.

Now got a full range of these plugs in stock...ready for shipment

Why not use B10EGV\'s they are just as good as the R6725 and are only a fraction of the price.....

:flamed

yip, thats what i heard too -the centre pin blown to kingdom come...

[BlitzBoy]

Remember if you intend to use B10EGVs you have to file down the spark plug socket to get them in on a FD

never seen NGK R740s or R725s do that been using them for years as many other high powered Rotaries.

Hearing and seeing are two different things

Sure, but a small price to pay for a plug that will do the same job for way less money....:Laugh

[BlitzBoy]

true but they dont last as long as they are not iridiums I believe so swings on roundabouts really, both work

[AtomicRex]

The R plug gives a much cleaner burn, and will last longer.
 
I think it is a case of what suits the application...
