my ep3 is about to tick 70k miles, and to the best of my knowledge, it's still rocking factory spark plugs.

I'm going to start doing the needed maintenance (fuel filter, spark plugs, timing belt, radiator fluid, etc)

which plugs work the best, in your opinion, for MPG's as well as performance?

and has anyone ever tried indexing the plugs? or would it be irrevelant?

thanks all.

OEM Honda plugs.

phyber

didnt know if NGK type stuff was still the best to get.

C Ory

Stock OEM plugs are NGK's.

Or do you mean is there something better?

phyber

idk. i been outta the loop for a while, since i was modding my d16

i know there's bosch platnium/etc's, denzo, etc etc...

C Ory

I'm pretty sure the stock plugs are NGK R's.

Unless you're F/I, I think that is good enough.

lol ngk all the way dumb question

phyber

what about indexing....is that something worth doing?

stay n/a

factory (rsx-s) is ngk ir which are great plugs, ive also had great results with denso ir power plugs as well but expect to pay 2x as much as ngk, i.e. up to $70 for a set. I saw that you had posted about bosch platinum stay far away from them they are shit in a k20 (and pretty much everything else) but trust me from personal experience dont use them
