Hey Everyone, im replacing the old Spark Plugs on my car, I spent $40 for these Bosche Platinum +4 Spark Plugs, Anyone Know if theyre gonna be any Good? If So What kinda of Difference should it make in My Sunfire????
if you do a search you will find that they are garbage. stick with delco or NGK plugs

Why buy them and then ask they are any good?? Search and you will save much heartache. Difference - itll be crap

be nice, we were all new at one point >.>
yeah I ran them once in my old car and I would never buy them again, buy the NGK G-Power I find they work just fine in my cavalier

Toss 'em. They work okay for a few months then they become total crap. The kragen guy said they would be the best and i was dumb enough to listen too.. ha.. i replaced them with ngk v-powers and haven't had problems with stalling + have a steadier idle as a result.

Sadly, no more..
I know several people on here that have used them for years and are more then happy with them. If they work fine for you then great if not follow the heard and stick to the AC Delco's. I won't say they are garbage I will however say to each their own.

I've used the Bosh platinum 2s & 4s and had good luck with them both. I haven't used them in a few years though.
Remember that having a good spark is great, but it won't add any power unless your motor was not burning all the air-fuel mixture in the cylinder. So plugs will not add any horse-power, they just ensure that you burn all the air-fuel mixture.
The bosh plat 2 & 4's will act like a regular plug, you will not get four sparks. The spark will travel from the electrode to the which ever of the four grounds has less resistence.
get your money back and go with ngk i did
i have had a set in my 2200 for about a year and a half. they seem to be ok.
i will be trying something different this time and then i will know if they are crap.
you have them now so use them for a while. your car will still run with them in. you just might be makeing 120 hp instead if 120.000001 hp.
I had them also, they were crap like everyone else is saying, had them on for two days and took them off and put Autolite XPs and have not regreted.
I havent taken them out of the Packaging yet, so ill Return them today and try out the Ngk's
I honest to God Bought these ones because i thought they were some of the best, lol. I Just Remember Going on to cardomain.com and seeing the Bosche +4 as alot of their upgrades, lol. My mistake. Ive also heard from alot of people that the Stock ones might be better neways? is this true? Or will these NGK's help with fuel mileage or anything. I just dont wanna sacrifice say performance, for some gas mileage.
i use NGK because of the nitrous. just stick with your stock plugs

Im a Xbox 360 fanboy...and damn proud of it!!
i use ngk's because it gives me a smoother idle and luv these i think ill start buying these permanently NGK platinum

Wow sounds like know one likes them. I personally love mine car was running rough and was miss firing and so forth i put platinum 4 in mine runs great been in for over a year no problem with them. THey improved my fuel economy to. I don't know about the ngk never ran them.
2nd Place is the first loser
I have used The +4's for 6 years now and have had not a single problem. As stated by Jackalope, to each their own. I use them and have been and love em. Just one thing though, $40 for four plugs?? You got took on the price unless you are in Canada. I paid $25 for my new set last year.

I\ have used +4 +2 for Bosch and when i went back to AC Delco my car ran a better with the AC Delco. I spoke with some V8 crowd people and they hate them. There is no way to gap them properly you get what comes out the box and if a electrode is a little shorter electricty takes the shortest path so you won't get the 4 electrode firing. When kid came to buy some Bosch +4 at pepboys and some muscle car guys were there they just laughed to hard. THe kid went on like he was going to get major HP. There is no gain from plugs for a NA car.

And as such there is no loss either.
