DENSO Iridium TT Spark Plug - IKBH20TT - Twin Tip - The Powerful Premium Quality Ultra-Efficient Replacement Plug Fits Lexus ES GS IS C LS RX RC LC, Toyota Crown Camry Mark X

Great buy. Original

Legit item, works as it should.

Immediately noticed a performance increase after installing these plugs in my 3rd Gen Tacoma. Not disappointed!

Definitely worth it to buy, my husband bought boshe I think its called but the lower end of boshe and it kept causing our truck to missfire. Both brand new, but Denso did its job. No more deceleration on the RPM when its idling.

I used these to replace plugs on an 18 sienna. I noticed after I received them that it was not the OEM part number but after a bit more digging found that they still would fit. I'll tag on the same complaint with the packaging for these. They were in a regular paper package and inside small little cardboard boxes. Would be easy to damage them or mess up the gap. But in my case they all turned out fine. I still had to adjust the gap slightly. I know all the packages say not to but I've had no problems as long as it's just a slight adjustment. I feel like the engine ran quieter and had a bit more power after replacement. I'll likely use these again when I get to the change interval later.

Though my car and motorcycle are listed with Amazon, additionally, with an extreme schedule at 69 and an invalid wife and having to work Door Dash to supplement S.S.I. I tried to cram oil and coolant change with cabin filter and service my K&N air filter with a new dash cam to boot plus plugs at 106,000 miles, Though I crawl on the ground to do my own work as is needed, these plugs I bought did not fit in my car. I tried to do all of this as my energy and schedule permitted on 5/21/25 which put me 2 days past my return eligibility. So I had to plop down $70 more at O'Reilly's Auto Parts to finish the job yesterday 5/21/25. Responsibility to get out and do the job within 30 days of delivery should not be the issue. With whom the fault lies re: the ordering of spark plugs should also not be the issue either. If we were of child bearing years should I make a mobile with these plugs to amuse our new baby? If they are the wrong plugs I should be able to return them for a refund as long as they are (a) in new condition. (b) have undamaged packaging. (c) have not been replaced with "New & Improved" making these plugs obsolete. I want a refund. That's All FOLLOW UP. 5/24/25: After several attempts to arrange a funded return I was speedily assisted through Amazons chat customer service. The person who helped me lent a listening ear and the reasons that I could not just stop what I was doing the learn that I had the wrong plugs. Within ten minutes my situation was resolved. Thanks Amazon & Allan!
