i needed to upgrade, all i could get my hand on were the Bosch Platinum 4's and im highly pleased. I noticed the very meager difference immediately when it came to the power. Also, i noticed a marginal difference in the gas mileage as well.
Seem like almost everyone here go for the stock plugs. Bosch W6DPO. I'd just got mine, no need for gap as it good to go from the box. The electrodes face each other horizontally instead of typical vertical that we normally see on other plugs for other cars.
Im running bosch +4 in my 2.0 with Blue ignitor wires and they work great.
the Champions are really surpassing my expectations!
I bought Champion Copper's....they're like $3 a pair, and she pulls like a SOB. I just replaced the Champ with the exact same....save ur hard earned $$ and spent it on wax or lights or some other accessory to make her stand out
Same here. I had the Bosch F7LTCR's in the car when this happened to me. I'm currently using autolites and am very happy with them so far.
I too happen to have the champion plugs that iceman has. Happened because Murray's didn't have the dealer only replacement plug and couldn't get them. I had no choice because the stock ones were blacker than my tires. They rev just fine and seem to run just as well. I was told that a long time ago champions were known to become permanantly stuck in the block though. I plan on changing soon just in case that rumor is true.
I just put Bosch Copper plugs in my 2.0 L Passat and it's running like crap. I think I forgot to gap a couple of the plugs... Would that explain the rough running engine?
i have never heard a good thing about the Plus 4's, lots of the VR6 people stay away from them. one of my VR6 buddies had some that were trashed in a short period, nothing wrong with his car just the VR didn't like the plugs. i have had them in my Frontier and pulled them out after about 10k miles they looked ok but truck didn't like them. yes they were gapped correctly, went back with the NGK's that were OEM and truck ran better. better how? smoother, no hesitation and all i did was change plugs back and forth. nothing else was done to the truck. i know this post is vague but i don't have any techie stuff to back it up, what i am baseing this post on is experience with my Nissan and witnessing what my buddy had happen. yes the plus 4's have a lifetime warranty and are not that pricey, but i'll bet you won't notice any gain on mileage or performance, unless your current plugs are way past their prime.
They don't know how to make a good spark plug.
