Champion Spark Plugs

I am pretty sure I read the best plugs for a 05 4 litre is the Champion 4412, but I can't find them anywhere

Is there a better alternative?

Well, what was always recommended to me ( by Jerry) was the autolite app985 if you have a distributor less engine and the ap985 if you have a distributor. I run the app985's and they work wonderful.

I went with the NGK 3459 - ZFR5N. So far so good. I was told that the Champions were what came in the 4.0, but then towards the end Jeep switched to the NGK . . . I don't know if that's a fact . . . just what a mechanic I know told me. He mentioned that the Champion would be fine, but from the engines he's worked on, he felt the NGKs held up better and mentioned that they'd usually look new after 30K. Stay away from the Bosch Platnium that just about every auto parts store that I spoke with recommended . . . I hated them and pulled them after 10K.

x2 on the bosch platinum. Every store recommends them, I put them in and pulled them at my next oil change. Ran like crap and looked like crap after only 3,500 miles. I have the autolite app985's in there now and they are worlds better than the Bosch.

If you want to go with Champion, go with their 7034 which is a double-tipped platinum plug that works well in your newer distributorless engine. If they don't have the 7034, go with the Autolite APP985 (not the AP985!). Either of those plugs will work superbly and last pretty darned close to 100K miles.

Yep, avoid Bosch plugs... ESPECIALLY their Plus Two and Plus Four plugs which don't work well in our Jeep engines.

I just got it a little while ago, it has 45k miles. I haven't checked but I am guessing they are the stock plugs. If so, do they need to be replaced? I wouldn't mind doing them anyway.
I notice that if I gas it, it hesitates a little, then bogs a bunch, takes off...a little, then falls on it's face, or is that just normal?

45K miles on the stock plugs means it is time to replace them.

Great. Thanks. I should have looked at them all prior to buying the jeep, but now I will get to see them. It gets 19-20 hwy so I am guessing there is nothing wrong with it.

Didn't say Bosch didn't make good quality spark plugs, we only said they just don't seem to work well in our Jeep engines.

.035, though they are likely pre-gapped to that and should not need any adjustment.

Went with the autolite app985. Runs great, thanks for the advice.

Infernogirl, if you were not so far away I would do them for you

Seriously though it is a pretty easy job.

Autolite app985 (not ap985), it's what I run in my 2.4L they work great. You want the double platinum.

Your TJ is a '99? If so and you have the four cylinder engine, your engine is the 2.5L which is a completely different engine than the newer 2.4L is.

Your 2.5L will do fine on the less expensive Autolite AP985, it doesn't need the more expensive APP985 like the newer distributorless engines do.

I think this is an appropriate forum to post this. Good to know Jerry as I haven't even looked at my spark plugs when I bought it and have 64k on it. Also when did the Jeep 4.0L go distributerless?

Some time around 2000-2001 for the 4.0L engine. Hah, I saw that "sticker" yesterday. Funny, my wife doesn't feel that way at all.

Yea if you have the 2.5L then I can't help. The APP985's work good in the 2.4L without a distributor.

Rebate on Champion Plugs

Finally got around to buying new plugs. Shopped online and $5.99 and up for Champion 7034, as recomended. Pep Boys were $3.99 AND are offering a mail in rebate until April 4th. $2 per plug for double platinum 7034. Not a bad deal. I assume its everywhere but at $1.99 per plug it's worth checking out IMO.

I know this thread/topic may be considered a dead horse but for the record the champion 4412 Truck Plugs are still available. At first I couldn't find them so I bought the Autolite 985's (not app) from Kragen/O'reilly for .98 cents each. Sure enough they were made in China. After searching further I found the 4412's at Carquest in Yucca Valley. DAP Auto parts in Costa Mesa also carries them. The guy at Carquest explained the reason they are called truck plugs is because they are "heavy duty" and built beefier than regular plugs. Because of this he said I should get better than 30K out of them. Incidentally the plugs I pulled out were the plain 985's, which is what the Kragen computer said to use in the '99 TJ. I don't know if they were the original factory plugs or not. I changed them at 66,000 miles, which was when I bought the jeep. I'm really happy with th 4412's. Incidentally, neither here nor there, the Champions look really cool. Black porcelain and gold. I'd never seen a black spark plug before. And they are made in the U.S.A. I paid $3.99 each for them. I know that sounds high but my TJ is worth it.

I just put in the Champion 7034 plugs today to replace the Bosche +4 that the previous owner put in the Jeep and it runs tons smoother. The came gaped at .045" so I had to reduce this to .035", but that is no big deal. I could not find any stock on the Autolite APP985 anywhere. They were all special order plugs. The Champion 7034 I got locally at Checker/Schucks/Kragen for $4.09 a piece with a 5 year warranty.
