    E3.54 is rated 4.4 out of 5 by 12.
    Rated 5 out of 5 by from Wow Noticeable difference in the performance of my Z06 over what the previous owner installed. Better throttle response and near immediate startup. I would buy these again, definitely worth the money!
    Date published: 2020-05-29
    Rated 5 out of 5 by from Good! Installed these myself and noticed a much better throttle response and I believe my mom is a bit better too. My old plugs and wires were toast tho. Would recommend Jegs and E3 Spark plugs. Arrived quick as well!
    Date published: 2018-04-20
    Rated 5 out of 5 by from LOVE EM!!!! I swapped out all the plugs in my Avalanche with these. The old girl has 150,000 miles on her and was driving like she was really tired. I put these E3 plugs in, and HOLY SMOKES!!!! Like a complete motor transplant. Brought her back to life!

    Rated 5 out of 5 by from Great Plugs After I started using these spark plugs I would never go back to standard plugs. No gaping needed, better throttle response and seems like more power. Love them

    Rated 5 out of 5 by from Mohr Powr!!!!!!!!! I bought these spark plugs about a month ago. I haven't noticed any better gas mileage but the increase in power output of my engine was immediate. My car now reacts much more quickly then with the old plugs.
    Date published: 2015-08-26
    Rated 4 out of 5 by from Works well. Spark plugs are difficult to evaluate, I haven't even run one tankful of gas yet, but I know I have more power, easier starting, and better fuel economy just by how much better it runs.
    Date published: 2019-10-15
    Rated 4 out of 5 by from more power I only have about 50 miles on these since I installed them in my vette,so it's too soon to give them 5 stars. Car does seem to have better throttle response and have more power. Have to wait and see about the mileage. Maybe later do an update.
