Denso (5356) IXUH22I Iridium Power Spark Plug, (Pack of 1)

These Denso Iridium Power spark plugs are excellent quality and a great upgrade or replacement for many vehicles. The iridium design helps provide a strong and consistent spark, which can improve engine efficiency and smooth performance. Installation was straightforward and the fit was perfect. They are well known for durability and long lifespan compared to standard spark plugs. After installing them the engine runs smoothly and responds well during acceleration. Pros: • High quality iridium construction • Reliable and consistent spark performance • Long lifespan compared to standard plugs • Improves smooth engine operation Cons: • More expensive than basic spark plugs • May not provide noticeable gains if replacing newer plugs

Very good quality

My 2017 Kia Forte was throwing out ignition error codes, so I replaced all the ignition coils and spark plugs. They arrived quickly, seem to be of good quality, and installed as expected. This happened about two years ago, and I have not had any issues since, so I would say that they are performing well.

These were purchased for my '10 Element. Thousands of miles later...still going strong! I also replace the coil packs using Denso. All work flawlessly. Big Rudy

This spark plug worked very well as an OEM replacement in my 2010 Mini Cooper S. I saw in the mechanic's notes from the previous owner, saying that they should be replaced, and they definitely made the engine run just that little bit smoother. If your engine is turbocharged like mine, you'll want to run a smaller gap than what these come at, so make sure to look for the proper gapping instructions for your vehicle. One other note specific to Minis: the plugs that are standard in your car are a 14mm 12 point design, and these are 5/8'' 6 point. Make sure that you have both in spark plug socket form before you start, and you'll be good to go!

Arrived in brand new condition sealed nicely. Perfect fit and OEM spec for 2016 Kia forte sedan. Great price verses auto parts store and much faster shipping than rock auto.

The spark plugs are super good. They lasted over 100,000 miles

I think its a great Plug , have a 09 Acura TSX 6 speed with 61,000 on it . I thought it was time to change plugs, to see if I could pick up a little better gas mileage . Now im using Winter gas and 4 snow tires .. I was getting about 25.4 before I changed plugs ,now im getting 27 .6 or better ...got 27 MPG at 77 mph on a 120 mile trip. Depending on speed I can get 28 Mpg..Also you can feel the it accelerate quicker of course they are new plugs but all said and done ..Good Plug . Now my stock plugs were DENSO iridium also but not these

Went with the best ones for my car

Thank you!

タントカスタム(LA600)用に購入しました。消耗品なので、もう少し早いタイミングで交換するべきでした。

Great product!
