BTW, the P/N for the irridium version of the "extended reach" plugs is ZFR5FIX-11.

Remember that not every auto parts store carries NGK or Denso plugs. And, of the ones that do, they won't stock every part number (usually just a selection of the most popular ones). Just don't expect to waltz into Walmart and come out with a set of good quality spark plugs! But, if you live near a Murray's or Napa, you may just be in luck...

all the plugs are about the same, but I did dyno runs of ngk vs. bosch, the results were surprising, but so minor that it really wouldnt matter unless you were really going to fight for 1 whp in your upper and lower powerbands.
Nothing is a waste of money if you have the money lol
but if you dont then stick with stock.

NGK copper plugs are best suited for what we've got. Anything else is throwing money away IMO.

Hey I'm new to the forum. Recently I had a few probs with the spark plugs in my 2001 Protege 5. I replaced them with Bosch platinum plugs in Dec 2005. About a month ago I had to have them changed back to NGK's. The mechanic said they were heating to hot. He went ahead and replaced them. I drove away from that place and less than a mile away the check engine light came on again. Anyhow, I ended up taking it to the dealership and they replaced the ignition coils cuz they said they were bad on cylinders 2 & 4. Was it a bad idea to put the platinum plugs in and would this have caused the coils to go bad?
Oh and NOW....I have another check engine light and the dealership is telling me I need to replace the catalytic converter.

Hi, everyone! I'm a newbie to this forum, having just purchased an '03 Protoge5.
The car currently has 28,000 miles & according to the maintenance log, is due for new plugs at 30,000. Is this correct - seems a little early to me! What brand/type plugs do you recommend? Is this a "do-it-yourself" project or do I need an expert?
Thanks for any help you can give me - I look forward to sharing a lot of good info with you all on this Forum!!
