Why do these only say 2001-2004? If they fit those, shouldn't they work on my 2000?

I need these asap, there's a few other auctions with same style/price ones and they state they fit 99-04.

Thanks in advance.

Price seems to good to be true to me, but maybe that's just me. I would take a look a summitracing. They have a pretty fair price on cop and you know what you are paying for. Anyway they should fit your 00.

I emailed seller and he said 99-04 is fine. These are the same ones the COP sticky said are fine as replacements. Even if they only last 30K or so miles, I won't mind. I'm only misfiring in cylinder 4, but I don't like band aid fixes, gonna do all 8 plus the plugs.

Now which spark plug to buy, hmmm?

Well I bought the Ebay cop's and also a set of NGK's you all seem to recommend around here.

Here's to the plugs being dry and not wet with oil or coolant. *crosses fingers*

you might of been better off just buying a single OEM cop and replacing the broken one. That way you know at least its something of quality.

Well too late now haha.

I normally wouldn't mess with ebay stuff, but when trusted members here say that most of the COP's are made by the same company, and there is a sticky in the DIY for COP info stating these ebay ones work just fine? I'll go with them. For 80 bucks shipped for 8, can't go wrong.

IIRC, someone did a comparison of COP manufacturers and found that all of them are made by the same manufacturer, just with different 'specs'. not sure if that applies to these ebay cops, but i wouldnt be surprised.

just keep us updated, and let everyone know how they compare to OEM.

^Will do. I am certain they won't be as high quality as the oe motorforce units currently in the car, but if they crap out, the vendor says "lifetime warranty," so I will just get my 80 bucks back and buy something else.

It's in the COP sticky, quoted here:



Beyond all that I have tested the OEM COPs and verified that they can produce 55 kV in air at STP--and in that the gap ionises at 18 kV to 25 kV max (even running a whole lot of boost) the stock COPs are entirely capable of doing the job.

The days of under-powered stock ignition systems are long gone...



BTW/FWIW, using the same test setup the best the Accel COPs could come up with was 48 kV. Here's a photo of a Weapon X COP being tested, it hit 66kV maximum:



That's a 42A 12V supply on the left, my tester, and the WX COP connected to an adjustable air-gap plug tester--and a couple of Accel COPs on top...
