I was wondering if anyone has tried these? I put some in wife's corolla @120ish w/original denso's still in car. I can honestly say that these are by far the best spark plugs intohave eever used. I have tried them all over the years.
The "guy" I bought my cl-s from said he just changed the sp b4 u bought the car, but I am finding more & more things w/car that are not true or he didn't tell me about.
So I am thinking of going withthese . Just curious if anyone has any issues or problems?
I couldhhonestly tell a difference in wife's car w/mileage going up, and a lil more umph to motor.
Thanksin aadvance. Joe

 

Ive found through research that the e3's are pure marketing.
stick with the stock NGK's

 

Pull A Plug And See What it Looks Like.

I Would Only Use the Recommended Plugs.

 

with the others. Stick with the stock plugs. They will last the longest, and you wont benefit from the other plugs and the gimmicky marketing

 

Junk. You only saw an improvement cause you replaced worn out plugs on the Corolla.
Stick with OEM. They are good plugs designed to last 100K miles anyway.

 

i learned you can not go wrong with oem plugs

 

OEM or go home on plugs for this car.

 

iridium ix or laser iridium

 

I used NGK plugs or something .
