Denso (3297) SK20R11 Iridium Spark Plug, Pack of 1

Worked great on my car, no issues at all! I've already put 5,000 miles on them. Thanks, Amazon, for the next day delivery. My car wouldn't start, and I knew I needed to change them fast. They fit perfectly, and the price was great too!

OEM quality and performance.My performance went up 15% after my previous one of 100k miles.Denso makes quality product.Fits my car as described

1991 Lexus LS400 - When it was time for me to buy spark plugs my Shadetree Mechanic advised me to buy iridium type spark plugs. I didn't know what Iridium Spark Plugs were so I fired up the old computer and went to Amazon to investigate. Wow! These things sound great! I first found the Bosch Spark Plugs. They are "Double Iridium"! Two is better than one right? Also, they are named after that macho LA Police Detective on that show! How cool is that? I hope he's getting residuals. So, I wanted to get those. My Shadetree Mechanic, who is wet blanket when it comes to getting cool car parts, said no, you don't need Double Iridium Spark Plugs for your car. They are are a waste of your money. I said, but if single iridium spark plugs are supposed to last 100,000 miles or a 1,000 years, whichever comes first, then the double iridium tipped ones will last 2,000 years! You're a man, isn't more always better? My Shadetree Mechanic then gives me the look of, I'm going to charge you double for you insolence you crazy occidental if you keep talking this way. In order to win my argument I made a last ditch effort plea. I said, If I cheapen out my car will know and she will leave me! My Shadetree Mechanic then charged me twice for my back talk. Life goes on. I recommend this brand of spark plug for your 1st Generation Lexus

I bought these to replace the factory spark plugs on my 2005 Camry 2.4L I4. I'm at around 58K miles but the original plugs are about to hit 11 years old. For the price, I decided to just replace them. I wasn't seeing any particular problems except for a slight vibration at idle w/ the AC on but I consider that completely normal. I didn't want to leave the originals in for 15+ years and not be able to get them out, despite Toyota saying they are good for 100K miles.Steps for the Toyota 2.4L:- Remove plastic cover from top of engine (if equipped)- Remove coil pack boots- Remove old spark plugs (mine were NGK)- Install new plugs- Put coil pack boots back on- Put plastic cover back onThis was my first time replacing spark plugs and it was very easy! As my car gets older I am learning how to do things on it, like brakes and whatever else. I changed my PCV + PCV hose along with my spark plugs and the car feels better. Gas mileage is the same, pretty crappy in the city but I drive "spiritedly" - idle is smooth, engine runs quietly.I opted NOT to put anti-seize, I read online that there's some kind of coating on the plugs already and that both Denso and NGK advise against anti-seize as well. It has to do with it changing the torque values. If these plugs last another ten years, I will probably get rid of the car before I ever have to change it again anyway.Overall, very happy. I think the price is fair for iridium tipped plugs that will last 100K miles. My factory plugs still looked very good after 58K miles / 11 years so I have no doubt that these will last a while as well.

It's the first time to replace spark plugs by myself. After watching youtube videos, it was easy to install the new spark plugs in my 08' Toyota Camry Hybrid, which had 125,000 miles on it. I tested starting the engine right away without problems after the install. Haven't noticed any changes in MPG. took one star off because one of the spark plug tip looked not well aligned by visual inspection, and I didn't know how significant this was so I went ahead with the installation. didn't measure the gaps.

Great OEM quality plugs for my 2005 Toyota Landcruiser 4.7L V8 (UZJ-100), these are made in USA from US and Japanese parts. They went into a truck which had 105k miles on it and never had the plugs replaced. Note they are 16 mm plug size, so you will need to use the 5/8" spark plug socket (it's pretty rare to find a 16 mm spark plug socket stateside) None of my old plugs were seized (old plugs were NGK from the factory) and I retorqued them to 14 ft/lbs per the FSM.I found on my truck that the 2 plugs closest to the firewall were the hardest to get out since I didn't have a shorter (4" vs 6") extension and the plug + socket + extension + wrench would hit the brake booster (driver side) or the firewall (passenger side) so I had to monkey around a bit to get them out. I did replace the ignition coil boots and grommets with the Denso kit #671-8484 (this sadly no longer made in Japan or US, but in China), but does seem to be comparable quality. Oh to access at least on my truck the passenger side plugs, I had to take the intake manifold off (two 10 mm hex screws and disconnected 4 hoses).
