Spark plug Bosch or Autolite

I've had luck with Bosch Platinum+4, and also Denso Iridium plugs. My advice to you is just stay away from the cheap stuff. Like "Wally's discount Spark plugs." Stock wires do just fine with any plug for your car.

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.

Seems like you did everything except swap out a $2 spark plug. I had a misfire on cylinder #1 first then cylinders #3 and #4 until I went out and bought 4 new Autolite 3923 spark plugs and put them in and BINGO no more problems the car is running strong and not throwing any codes.

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've run the platinum +4s in my GTI and I haven't had any problems but I haven't found them to feel any different than any other plug.

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.

I always been using Bosch Silvers on my car, but don't last very long.
