Owner reviews for spark plug

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.

OK it is now monday and I changed the plugs on friday I tested the power this weekend and it seems like it was the spark plugs..... The power I had lost was to much after I changed the plugs I felt the difference....... NGK platinums are the sh*t.......

NGK a little bit pricey but well worth it.

i just installed the factory NGK's... love'em , a little pricey though

I've got the BKR5EUP and they are great. 15k miles with no noticable wear.

i've had the beru ultra x's in for about 8K...no problems...no noticeable improvement either...starts the same (good), runs smooth...no complaints, but no better than stock...

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.

Just be careful with the Denso plugs. Denso has the gap specified incorrectly in the database so the gap is larger than they should be. It'll run but my cause to long term problems such as coilpack failure.
