DensoSpark Plug Iridium TT - 4705

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 AllFOLLOW 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!

As described. OEM quality product.

Perfect

True Denso. They have worked great since I put them on my 07 IS250 in August 2024.

I installed these on a 2018 RX 350 at 60k miles. Not an easy project, as you have to remove the intake manifold. What I found was that 3 of the factory installed spark plugs were barely hand tight! I thought the engine ran rough. Anyway, after installing these, it runs perfectly.

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.

Checked the gap on the plugs & found every plug needed adjusting for Lexus RC350 F Sport.
