Durable yet manages to boost my car's performance a lot. The idling is very smooth now and my car is practically purring now. Acceleration also happens immediately and there are no misfires. Starting up the car is also much faster now. My car emissions have also gone down too.

My fuel consumption has gone down ever since I installed these plugs. My idling and acceleration is smoother, and the pickup is faster. The best part is, these plugs are cheap and really, really worth the low price tag it comes with.

I noticed a pretty big fuel saving when I installed these plugs in my ride. The engine runs very smoothly and frankly, I have no complaints about them whatsoever. These are great, hi-quality platinum spark plugs that are dirt cheap considering the fuel savings and the overall performance boost it offers.

I have used the G power plug from my BMW's to Honda's. They have worked flawlessly with no complaints. I have used different brands in the past but causes rough idling but these works fantastic! If you purchased these, it definitely wont disappoint you!
