Enhance Performance with DENSO # 3461 IRIDIUM LONG LIFE Spark Plugs - SXU22HCR11S (4 PCSNEW) Review

Easy to install. The dealer asked $240 to replace 4 spark plugs. Save money and do it yourself. All connectors are in-line and pre-sealed.

The original has served for several years without complaint, so I wanted to replace it with exactly the same. The seller's price and delivery are also excellent.

Description says OEM but I had to buy a different head because the spark plug was different for the 2011 Mini. I've been able to use them but won't recommend them as an OEM or you'll need a different outlet.

It was disappointing to learn that these Denso spark plugs were not made in Japan. As long as they work well I don't know how long they will last compared to the OEM that came with the 86000 machine. I will be more careful to make sure I get the ones made in Japan.

Although Revain says they won't fit my car, they do. Check the Denso website for the correct part numbers for your vehicle. Then find Revain for the part. Revain's Car Fit is often wrong. Time will tell how well these plugs will hold up now that I've installed them. PS: You will need a 16mm or 5/8" spark plug socket.

factory spark plugs. you are doing great work Changed at 100,000km. The old ones looked really good. The electrodes did not appear optically eroded; However, I did experience rough revs, especially with the A/C on and off. After replacing the spark plugs, the jerking went away - although of course the power resistance of the compressor remained.

These spark plugs will NOT fit my 2003 Acura RSX, despite what Revain claims in the Your Garage installation results. DO NOT trust their results, always check with the manufacturer or other reliable sources of auto parts. These return. FYI the correct OEM Denso Iridium spark plugs for my Acura engine are: SKJ20DR-M11.

They were bought for my Mini Cooper where a 14mm socket was needed to pull out the original plugs. These Denso spark plugs are 16mm in diameter. Revain offers a bundle purchase of plugs with a 14mm jack provided they are 14mm plugs. It's not like this. My 16mm deep socket fitted my Mini's spark plug wells, but it was difficult to turn the head by hand or with a ratchet wrench. The workaround was to use a bench grinder to reduce the diameter of my 16mm head. This prevented Revain from being…

I've been using a standard 15mm mini fork socket since I bought the car five years ago. However, these plugs are hex and require a 16mm socket. The standard 16mm head is too thick to fit in this space. So I ordered a 14mm 12 point head hoping it would fit but I doubt it. Just take a look. If not then I'll be mad because Denso says they fit in my car. "Fit" to you Denso folks means I should be able to tighten the plugs. When 12-pt 14mm doesn't work, I go to P on Denso from every possible place…
