Sparkplugs
 

I was wondering which sparkplugs everyone is using and why?
I am going to get new ones soon and want to know which are best.

i run ngk coppers in my 924, the platinum plugs foul out so easy and I have always had great luck with then in my honda 350X.....i started running them in my 944s but not the coppers, just the premiums though. They do a fine job and easy start-ups

Bosch Platinum 2. The electrodes are like the Platinum +4's and they're a good bit cheaper. I've been running them for 30,000 miles and they still look pretty good.

I'd be curious to try the new Denso iridium plugs, except that they're about 10 bucks apiece.

If you drive Porsche or VW, or other European cars, Bosch Spark Plugs work best.
I think for your 924 go with Bosch Super 2 better than NGK Coppers.

I am currently using the Nippon Denso Iridium plugs on my 83 Porsche 944. It is much better than Platinum 2 or 4 so far. It gives good fuel mileage.

Those NGK , Autolite, etc. only work good for Japanese cars.

Ayone using these plugs?

How about Beru ultra-X?

huh.. you know i never thought to look.. not sure what's on my car and i've had it for 3 years! :P

i shall make it a point to look sometime.. lol

Certainly looks believable enough (actually, quite ingenious). I'd order them right now, except that they're $25 a piece. Good thing we only have 4 cylinders. They ought to make them with a Bosch platinum +4 style ground electrode.

I installed teh Bosche Plat +2 plugs in mine a week or so ago. The seam to work pretty good, and no gapping, the come pre gapped. GOt them at Autozone at 6 bucks each.

this looks similar to the nology ignition wires concept.
