Rated 1 out of 5 by RockyUSA This product does not fit my 2010 Mazda 5
This product did not fit my 2010 Mazda 5 with the 2.3L
engine. The thread reach was not long enough. The reach should be .98 inches.
Looks like it was well made but the threads were too short.

Bought these to install in my 1991 Chevy Caprice. It had been about 5 years since I last changed the plugs on the car. I changed these out along with the spark plug wires. Simple to install. It's been about 2 months since installing them and I can already see the savings in the gas mileage! Will definitely purchase again for my other vehicles. Plus I was able to get the extra 20% off deal that Pep Boys is offering on them when I purchased them!

I use these because power wise they are the only ones I notice an increased difference with when I drag race at Englishtown NJ and in my regular cars, they look kind of ridiculous, I've tried them against E3's and all the others, My gas mileage does seem to go down a hair but maybe that's just my aggressive foot, they don't crack apart like some plugs will over time and high RPM's if you want gas mileage go with Autolite Double platniums they are the best for that

I am happy I was able to install the Bosch platinum spark plug in my car. The car runs smoother now. It was a great deal from Pep Boys at the right price.

Rated 5 out of 5 by DTurner Great Spark Plug!
I have been buying these spark plugs for my Chevy's since they first came out. I will never buy anything else. 5 Star and I would recommend these to anyone with a Chevy. Not sure how they do in other makes.

These Bosch spark plugs didn't perform good in my 1998 Honda Civic. I will return them back to Pep Boys for a refund.

Rated 5 out of 5 by stefanzo Bosch platinum +4
Bosch is a solid spark plug all around. I installed them on a 07 Honda Odyssey and after only a week the gas mileage increased by 10% as well as greater acceleration and smoother idle.
I highly recommend it since they are found on most high end German automobiles.
I know I'll be fine for another 100k miles.
