Denso SK20R11 Iridium Spark Plug Review

Did you know that with engine code p0505 you have too many other variables contributing to fuel economy? Longevity. I'll tell you in 100,000 miles. These are pre-gap folks on .44, so confirm the gap, install it and go. Smooth.

These are the original spark plugs that were in my car and lasted 203,000 miles. I probably should have replaced them at 150k but they worked and you know the old saying "if it ain't broke" but the coil packs failed so I just did both. I think if they last that long it would be a good idea to buy again.

So they clearly aren't designed to bring more romance into your love life than I'd like to believe. who knew I hooked it up to an AA battery, showed it to my wife, nothing. Come on, worked great in the Siena '04, it just sucks getting to the rear three cylinders behind that wiper.

I installed them on a 2003 Sienna. As mentioned, the OE spark plugs were NGK IFR6A11. Replacing the three rear plugs on this engine is a PITA, but it can be done - just search online. I had the confidence to do it and it took about 3 hours to replace all 6. They work just as well as the original plugs as expected and are slightly cheaper than the original boot plugs. My only beef was the delivery. They were shipped in a book box with no packaging, so the forks were knocked in transit and some…

Factory and brand new - perfect. Not used to that little spark plug but according to the specs and what the big boys say they should last at least 100,000 miles with no problems. The fit and finish is perfect and they went into the auto split with no issues. Now I'm a happy driver. I also ordered a 5/8" twist rosette to install and this is a cat meow for this setup with these connectors. Update 30th August 2015 I must add that I have experienced an increase in fuel economy of up to 3mpg on my…

I installed (March 2016) Denso SK20R11 iridium spark plugs on my 2005 2.4 liter Toyota Camry XLE. I bought a new car and after 110,000 km I wanted to change the spark plugs. In the process I broke two (2) plastic wire harness retainers. I used masking tape to keep them from falling apart. I used my air compressor and cleaned out the dust around the coils and in the spark plug chamber. After a lot of reading and debate online I decided not to use EP for the threads and tightened the new plugs to

High quality OEM plugs for my 2005 Toyota Landcruiser 4.7L V8 (UZJ-100), they are made in the USA from American and Japanese parts. They got into a truck with 105,000 miles and the spark plugs were never changed. Note that these are 16mm spark plugs so you will need to use a 5/8" spark plug head (in the US a 16mm spark plug head is pretty rare to find). None of my old spark plugs have been removed (the old spark plugs were from the manufacturer NGK). factory) and I rotated it to 14 ft/lbs on…

Lexus LS400 - When it came time to buy spark plugs my Shadetree mechanic advised me to get Iridium type spark plugs. I didn't know what iridium spark plugs were, so I booted up an old computer and went to Revain to investigate. Wow! These things sound great! First I came across Bosch spark plugs. You are "Double Iridium"! Two are better than one, right? Also, they're named after that macho LAPD detective from that show! How cool is that? I hope he gets leftovers. So I wanted to get them. My…

I bought these to replace the factory spark plugs on my 2005 Camry 2.4L I4. I've driven about 58,000 miles but the original spark plugs will soon be 11 years old. Considering the price, I decided to just replace them. I haven't noticed any particular problems apart from a slight vibration when idling with the air conditioning switched on, but I think that's quite normal. I didn't want to leave the originals for more than 15 years and not be able to pull them out even though Toyota says they're…
