    • Working well

    • My engine runs stronger with Denso TT plugs.
I first used these plugs in a turbo car. They work better under boost than standard iridium plugs. I tried them in a non turbo and found them to increase power as well.

    • Great product. Don't hesitate to buy.
I've used these in my previous car, Audi A4 2.0T, and now have them in my BMW 328i 3.0 I6. The Audi turbo was tough on plugs due to direct injection. That design produces excessive carbon deposits on plugs and intake valves. Iridium plugs last a lot longer in those conditions. In my naturally-aspirated BMW, I expect them to last 100k miles ... show more

    • Works Great in my '07 Rav4 V6

Review Image by steve hunt
worked like a charm on my 2007 toyota Rav4 V6. i was a little bit worried when i pulled the originals and they were a different Denso part number. But previous reviewers said it worked in their Rav4 V6 so i tossed them in. I've had them in for a week and they've been running great. i also replaced my ignition coils at the same time, and immediately noticed an improvement in acceleration. this was probably more due to the 11 year old ignition coils being replaced (at 142k); but i'll take what i can get. I do believe there is a special ring in Dante's Inferno for the Toyota engineer who decided you have to take apart the entire air intake system on the Rav4 just to change the spark plugs. and good luck trying to get a socket extension on the plugs in the back of the engine compartment facing into the firewall. ... show more

    • Good plug for Tacoma with 4.0 V6
Installed a set in my Tacoma a few months back. Unknown how the longevity will be but in theory should go the 100K. Noticed slightly better gas mileage (.75 to 1 MPG - yes, I check MPG at each fill up) and a little smoother under hard acceleration. Seem well made. Yes, I noticed left bank and right bank had different plugs in them from the factory. ... show more

    • Great Sparkplugs
Update: had to buy 1 sparkplug because from the previous set of 4 installed, one of the sparkplug's ceramic cracked, giving misfire issues. - - - - - - - - - - - My husband just replaced the original NGK iridium sparkplugs, and can feel the difference. Had to reset the ECU of the car, and that was it. Smoother engine, better repose, power. Highly recommend for Subaru Legacy. ... show more
