These plugs went into a '99 explorer 4.0l ohv and it ran like a different engine. Very smooth, instant response, better mileage. Great plugs.

I have used Bosch spark plugs before on my 1995 Mitsubishi Galant years ago and didn't have any issues with it. Now, its my 2007 Honda Pilot's (EX-L) spark plugs turn to be replaced I didn't hesitated purchasing and using the Bosch Platinum+ 4 spark plugs. Price of the Bosch spark plugs was more than half of the OEM NGK Iridium, plus it is made in Germany and not China. Install was a breeze with the right tools at hand and first start after installation went without any issues. No check engine lights, no misfires or any increase in idle noise and as a matter of fact I think it got more quieter. Now driving my Honda Pilot seems a lot smoother and has more power it seems specially when driving on highways. I will buy Bosch spark plugs again in the future!!!!

Bosch +4 spark platinum plugs. Made an immediate difference in performance and mileage, the factory plugs (Champion RC10YC4) had 86k miles on them. There was a noticable stutter at low speeds which vanished with the Bosch +4s. This is a Kia Rio not a Corvette, so any performance increase is noticeable and appreciated.

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.
