  • Male sure you get them in the box pictured
Make sure you get them in the sealed box pictured, box top was sealed shut, I opened it and inspected all four since this is my second order. All were in perfect, untouched appearance. Gaps all uniform, electrodes line up perfectly, gap appears identical in all four, and the firing end protected by cardboard tube. Also, these came in a 6x6x6 heavy made box with a few air pouches...well protected. My first order of four came in an envelope, no outter box like picture, haphazardly just thrown in, all four loose to move around in the envelope, two where actually out of their boxes just tumbling around in the envelope. Two of these four even had been gapped wrong and the electrodes did not even line up. Easy fix these used four are going back to Amazon and should have never been sent out in such shape. Hope the picture and the above that I went though to get four actually new, untouched plugs helps others. Accept nothing but the sealed box, otherwise you're likely getting problematic plugs like I did, send them back.These are excellent plugs, I have used these before and know this first-hand. I feel some if not a lot of the negative reviews come from subpar plugs being shipped and installed, creating running problems. I definitely recommend the properly handled, packaged, and shipped plugs! 💯 Percent. ... show more

  • Car runs bad. Came in unmarked packages, no brand name on the plugs.
Did not come in a denso box. All 4 in individual boxes with no brand on it. Not sure what brand they are, doesn’t say on the plugs or on the box each plug was in. Car has been accelerating strangely and running rough ever since I put these plugs in, I’ll bet they are not meant for 2006 Audi A4 even tho it says they are. ... show more

  • Run Great in My BMW
Excellent results so far. This was my first experience with this particular spark plug, and I really wanted a suitable replacement for the Bosch +4s the car came with originally. Which I was never a fan of, and I am also not impressed with NGKs most people use due to issues in anothe vehicle. Double check the gap, and of course, always replace the coil boots. I am happy to say my car is running great. She seems a bit smoother, and my performance and mileage is restored to where it should be. No issues on the scanner and all the monitors are exactly where they should be. I was not expecting any issues so I'm really not surprised. I do expect these Densos to last longer than the OEMs they replaced. I might amend this depending on long term performance. A bit of background, I am an ASE double master, and these went into a 1999 BMW 540i. ... show more

  • Made my engine idle rough
I have been hunting for the reason my car has been idling rough for weeks now. I had put these in a few months ago and my car was running great up until about a month ago. I didn't think that it was these because they had worked great so far. So after changing motor mounts, cleaning throttle body, cleaning mass airflow sensor and being on the verge of breaking down and taking this to the dealer/auto shop to inspect I decided to swap out these for the previous spark plugs. (I don't throw away car parts unless there is no salvaging them, I keep them for a back up) After removing these the car is purring like it was before. Maybe I had just one bad one but either way they didn't work for me. Hope you have better luck. ... show more

  • Fits my Highlander and it's what came in it!
I like NGK for years but can't beat Denso! Changed at 125,000 miles. Along with the timing belt, water pump(fluid flush), and alternator(it was Denso too). A different version of Denso iridium came in my 2006 Toyota Highlander. These new Denso are an upgrade! Much less pinging in the ignition. Also, I moved from 87 octane to 88. What a difference!!! MPG much better! Now I get 20 miles more out of full 16gal tank. Power is the same or a little better. My mileage is now at 230,000 and runs like a clock! Very smooth I can put a glass of water on the engine and it doesn't spill :) ... show more

  • Working very well in Saab 9-3
As anyone with a Saab will tell you, spark plugs and also coil packs are a big deal in these cars. You can not just throw anything in them. I've used these now in two different Saab 9-3 with the 2.0 turbo. One car has had them in for about a year now. No issues at all. The second I've had in for a couple weeks. Again, no issues and the cars are running great. ... show more

  • Worth every penny
I bought this plugs because I heard a mechanics podcast saying how good they were, well they were right, I installed them in my wife's crv without her knowing and when she drove the car she got home and told me that the car feels different, light and more responsive. So I guess it really works. BTW I got about 2 extra mpgs. ... show more

  • Original denso plug!!
Exactly, I want to plug, because I bought from Ebay ngk plug twice. All of faked item from china. All of thrown to trash box cant use it. Beware faked ngk looks original but looks carefully distinguished original plug.
