Look at getting some NEW spark plugs on the weekend. (NGK) 24V DOHC MIVEC

In the book at the shop it said that for all 6 Spark Plug it is the same model of spark plug.

BUT.

I have read that the Front 3 Plug should be Type:NGK:BKR7EKC-N
and the Rear 3 Plug should be Type:NGK:PFR7M

WHY IS THIS SO??

some ppl go the better plugs at the back as they are a bugger to get to so they dont have to change them as often.
but there may be a better reason for it

i think your right about that, same reason for magna's

So can you run the better plugs in the front as well?

Maybe this is why the book said the same plugs for front and back...

Post by **aza013** » Mon Sep 17, 2007 10:19 pm

yep front and back

they say to run the same front and back so you change them at the same time so you dont forget which ones you have done, and to get some more money out of you to

thats what I think any way

just get platinum plugs all round then you'll get a good spark and they are the best for performance.

Actually Iridium are the best performance but they don't last as long as plantinum.

we have a winner!! thats 100% true.

i have normals all way round. i dont mind changing them

the manifold is not really that hard to take off ive done it before. You just need to be very careful of the intake gasket

Are they the Iridium IX? If so, that's a lot cheaper then when I got them. I got mine for $17 bucks each.

I changed them over the weekend, you can really tell the difference from the standard.

I just went to AutoBarn and all they had were the BKR7EIX-11.

So if i just regapped the plugs to 0.8mm then they would just be the same as BKR7EIX ??

1.1 would probably be ok.
