Bosch +4 OR NGK?
Sorry if this has been asked before, but I cannot search the forums yet with my account. Did a spark plug change this weekend with Bosch +4's. Taking it out for a test drive has revealed that the engine is missing under hard acceleration and I had a brief check engine light episode. Should I trash the bosch spark plugs and try new ngks? I have had 0 problems thus far with my 99 maxima and am not a happy camper if bosch is to blame. I have 72k miles. Thanks in advance. JS

Yeah use ngk coppers. Plats if you don't want to change them as often (60k-plats, 30k-copppers), and are willing to spend more ($10-plats, $2-coppers). Others have also had problems with the bosch. Given that you have a 99, it could also be that you have bad coil packs (whether this could have been set off by the plugs or not I don't know) but 99's often have there coil packs go bad.

Thanks to everyone for your fast replies. Regarding the coil packs, I had noticed a slight miss under idle before I changed the spark plugs so maybe moving the coil pack around has worsened the problem? Anyway, Can anyone recommend a good place to purchase the NGK's and after I check my coil packs a place to get a coil pack as well? Thanks again, JS.

Terran...pep boys sells the +4's for $4.99 (just dropped $1 from $5.99) and you can get them even cheaper on ebay.
I am just saying when I swapped out my plugs 2 weeks ago and went with the plat +4's and I am very impressed.

Yeah and look into the coil packs. If you have to get new ones get the Mitsubishi.

Don't say we didn't warn you ahead of time.

After reading this thread on sparkplugs I ran out to look at my 83 max (that I bought in june and haven't drivin it more that a block) to see what kind of plugs I have. So I guess I'm going out to buy NKG's. I have bosh in it. The car hasn't been on the road in 2 years and at low RPM it seems a bit rough. Any thing else I should look at?

Bosche
Bosche Plugs are good, but the +4 is just a gimmick (remember split fires?). Go with the tried and true (and proven) of NKG's.
I also have read (many times) about people who replace with other than N's and have mysterious problems with runnability, power, gas mileage...you name it. They then go back to the N's and all is "corrected".
If you are DIY'er and like to experiment...try other plugs. If you only want to change plugs once...no question...NKG's are your bet.
Good luck!

I put a set of NGK Iridiums in last week, 2 steps colder for nitrous. Yesterday I ran my best 1/4 N/A time of 13.53 with a 1.98 60' also a new best. Next week I will try with spray and see how they perform.
This was on my 2k2, Part # is 2309 for the LFR7AIX
The main reason I went with the Iridiums is that 2 step colder plugs are not available in copper for the 2k2. Also NGK recommend Iridium plugs for nitrous and the 350Z guys are using the Denso Iridiums with good sucess.

You can split the difference between the NGK copper and $10 platinum plugs by going with NGK iridium. Longer life than the coppers, but better elecrode shape than the cheaper $4 platinums (G-power?). My car runs well with these plugs, then again my car also ran fine on the dreaded Bosch plats (1) that I discovered in there. Others have used the iridiums with good results though. I have a different gen car than you guys, but we all seem to share similar sparkplug pickiness issues.

Just wanted to say "Thanks" to all who suggested the NGK plats. I went ahead today and installed them and wow what a difference! Anyway, back to the auto parts store tommorow to return the damn bosch +4's. Thanks JS

Puting it simply, I need new plugs. I have an 83 2.4l max. I will be going out to buy NGK's and I don't mind spending the extra money. Will the Iridium plugs ($19.99cad) be an improvement over the Plats($8.49cad)? Or is it a waste of money? And have you guys heard of the NGK Hyper IXtreme($11.99cad)

There is nothing beter than the coppers. They are cheaper up front. They are cheaper in the long run cause $2 x 2 is $4 for the same everal longevity of the plats. Who the hel! wants to leave their plugs in for 60K anyway? You guys aren't true car enthusiasts if you do that. Back in the day people used to pull the plugs once a month. Going 60K without checking even the plats or Irids. could spell disaster if somehow one was faulty.

Glad to hear the original poster sorted his problem out. A guy on anandtech was complaining yesterday about the same issue - he'd gone from OEM to bosche. Everybody bad mouthed bosche (almost). I guess they really make crap plugs.

I went with the Iridiums just because I liked the ground electrode shape better. I'm sure the cheaper G-power plats are fine. Maybe NGK will go on sale again like it seems to do every few weeks or so.... Either that, or just shop around for a cheaper price.

Besides, I think they (usually) have a superior shape for both electrodes than most copper plugs.
I think it's rather presumptuous to say someone isn't an "enthusiast" just because he doesn't want to mess with the plugs that often and do things the way things were done in the old days. In the old days they changed their oil once a month and had to clean out oil bath filters too.... There is also something to be said for not disturbing and wrenching on engine and electrical components excessively.

Plugs don't go "bad" usually but they certainly show the overall health of your engine. The signs of running rich/lean are clearly visible through the plugs. In rare occasions there can be flaws in the strap. I can think of several friends that have had the strap melt away on them and thus had a misfire issue. Point taken on the olden days talk and I would agree that its not good to go disconnecting your coils every day. You missed the original point of my post. I made the mistake of going with plats. last time and the electrode was already showing signs of deterioration after 14K. The NGK coppers are v-power and many people here sweat by them along with many others in other venues.
