Could not believe the change compared to stock Denso Iridium and another reputable Japanese premium company's Iridium plugs I tried. Engine runs quieter and much smoother, pickup vastly improved, economy at least 10% better ! My car has a CVT - engine runs at much lower RPM, even under acceleration, indicating it produces more torque thus the CVT does not need to rev it to accelerate. Excellent product - also the value !

Great spark plugs for my Corolla. My car now has more power and gets a lot better gas mileage. I noticed a big difference right away from the first start. Only had them about a month now and i also changed the spark plug wires afterwards for even better performance. So far i'm very happy with them and would recommend them.

I bought a set of spark plugs for my wife’s RAV4 (2003 model) last year (2021). I felt the difference, very responsive, quieter when idling on gear engage. Now, I bought again for my every day car Yaris (2011 model) . I’ll be changing spark plugs this weekend.

The spark plugs are genuine Denso ones shipped from US. So, it was more convincing than those coming from China. They are of very high quality and came in their original box + each spark plugs were in their individual packets. The fast shipment was unbelievable. Highly recommended.

I installed last weekend and now I felt more power in the engine, really good spark plugs. I don't think need change spark plugs for long time, a little more save in gas too.
