Thread: Serious Issues 04+

bosch are junk plugs.

replace with AC delco or autolite iridiums.

NEVER use platinums.

Plugs probably aren't tight or the wires are lose. Those spark plugs suck too.

Bosch plugs? Thats your prb.

Copper core Autolite's would be the best bang for the buck.

For some reason and Bosch had documented it on their site at one time, their plugs get chewed up in our waste spark ignition system very quickly.

Take WOTGTP for example. his plugs were swapped in when he got the car from a dealer. A month later..he had misfires up the wazzooo. Swapped plugs and was a much happier camper, til his transmission died

This is a lie, as anyone that can perform arithmetic can attest to. Iridium spark plugs are the best bang for the buck. Over the course of 100,000 miles, you will save both money and time.

Coppers to get 100,000 miles: $2 * 6 plugs = $12 * 7 installs = $84 + 1/2hr labor @ $7.25/hr *7 installs = $109.38
Iridiums to get 100,000 miles: $8 * 6 plugs = $48 * 1 install = $48 + 1/2hr labor @ $7.25/hr *1 install = $51.63

Not to mention the couple hundred dollars (maybe $20/yr@12,000mi/yr) you'll save over the course of 100,000 miles in gas by using the more efficient plugs.

Wow maybe time to switch mechanics. It would have been better to leave the 4 in until you could figure out how to get the other two out. I'm guessing the boot cover was stuck and not the plug and your mechanic didn't want to deal with it. Still fail on the mechanics part. I bought NGK plugs and when I took out my old autolites they said NGK on them, haha.

Everyone swears that its right then they find that 2 of them are swapped after all and all is well.

Excellent point. If this is the case, then you've likely fouled out most of the plugs by now and will need a fresh set.

Pulsars are definitely a gimmick plug (what units is this snake oil salesman talking about?), but I don't recall hearing about them causing issues - there was a thread a while back where one of our member tried them and saw a very slight increase in gas mileage, but results will obviously vary (so many factors - weather, tire inflation, etc). Basically, you've got about the best plugs money can buy already. Save the $80 and call it a day.

Edit: We can all use a little search.

LOL, wow dude. You're trying too hard. It isn't a ****ing lie either.
I apologize let me rephrase, copper cores are the best bang for your buck with a modified car that is changed often.
People come to the forums to discuss modified cars, if your junk is stock, stick with the oem manual and gtfo.
