Review on 🔌 Denso 4704 IKH20TT Iridium TT Spark Plug - 1 Pack by Ben Balas

worked great on my 2007 Toyota Rav4 V6. I was a little worried when I pulled out the originals and they had a different Denso part number. But previous reviewers said it worked in their Rav4 V6 so I added them. I've had them for a week now and they work great. At the same time I changed my ignition coils and immediately noticed an improvement in acceleration. it was more likely due to replacement of ignition coils 11 years ago (around 142,000); But I'll take what I can get I think there's a special ring in Dante's Inferno for a Toyota engineer who decided you had to disassemble a Rav4's entire air intake system just to change the spark plugs. and good luck trying to get an extension socket on the plugs in the back of the engine bay opposite the firewall.
