Try em you’ll like em! Works for me!

Maybe I really Want to feel an improvement in performance in my older Honda, so I do. To me, there is more consistent pull when getting on the highway now. Maybe because the other plugs were worn out? Anyhow, I bought a set for our Toyota too and both seem to be better performing.

Amazon did not package the product properly!

Very Very bad packaging !!! The plugs were thrown into a shipping envelope in their original cardboard box. Each plug in it's own little box! When I received the package and opened it 5 of the 8 plugs were out of their box and loose in the envelope. Problem is although they look OK, no porceline cracks I will not know if they are good until I install them.Good job Amazon.I've used E3 plugs in the past and found them above and beyond other brands.

3.5 v6 Tacoma

Compatible with the 3.5 v6 Tacoma so I installed them. Later learned in the service manual to use ONLY IRIDIUM Plugs. These sicken the engine ,.... .rough idle, poor acceleration, felt a miss occasionally, lost some hp/mpg. Purchased Denso IKBH20TT plugs which fixed everything. Worse part, installing plugs in the Taco is grueling but do it twice is torture.( the design of the E3s are archaic, like arming WW2 soldiers with flint locks rifles.) Install the E3 plugs if you insist on ruining your engine.

No power gains but work well

I didn’t get any power increase or better gas mileage; however, I did get some very nice spark plugs that work well. The price was excellent and I would buy them again.

E3 r the best plugs

I have a set of this in my 2015 Prius. They have over a 100,000 miles on them and they are still rockin and rolling in that car with over 219000 miles on it. I put a set in my wife’s 2018 highlander with 97000 miles on it. So it will be a while before I change plugs again. Damn good product from E3 products
