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

Perfect fit, works great, lowered gas usage, improved mileage. Highly recommend.

I bought 10 pcs of these (6 for a 2006 ES330 and 4 for a 2002 Camry) and they fit and worked excellently. Throughout my time with both cars, I had no issues related to spark plugs (or misfires, for that matter); they fired on the first attempt, without any challenges or drama. Both cars also idled super smoothly, ran quietly, were powerful (for their engine size), and I got impressive gas mileage out of both vehicles, right up to the last day. Sadly, I no longer own both vehicles, but their present owners are still enjoying the superior iridium power these spark plugs ensured. If I ever need to purchase these spark plugs again, I'll do it without ANY hesitation!

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 on This 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.

Old plugs of same make had 115,000 miles, they showed little wear compared to new ones, great plug, long lasting.

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.

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!

I have a 2009 Toyota Camry 4 cylinder with 87,000 miles on it. About 10k miles ago I noticed rough idle, less than optimal acceleration and mileage. I bought these from Amazon, installed myself. You need a 10mm socket for the plastic head cover and spark plug wire heading locks, and 5/8th socket for the plugs themselves. They all came properly gapped (.43mm) but you may want to check yours when they arrive. These plugs IMMEDIATELY fixed my rough idle, acceleration, and mileage. I checked the original spark plugs which were NGK. NGK is an excellent brand but the receptors were well worn and probably contributed to the problems I mentioned above. This is not a criticism of NGK, its a great brand...but I've read a lot of internet message boards and people say you can keep the original OEM plugs in for over 100k miles. This was not my case. Mine probably needed changing at 70k to 75k miles, and I'm glad I didn't listen to this advice and replaced them when I could sense the engine wasn't running at an optimal level. I'm getting better gas mileage (probably 5-7%% better) and better performance as a result. I forgot which vendor I got them from (it wasn't Amazon, but bought these on Amazon), but free shipping via UPS arrived 2nd day! Great service, and I was worried because Amazon never seems to keep these in stock but was happy with 3rd party vendor...sorry I forgot which one it was.

These plugs are outstanding the power and gas mileage I get from them is very good so I would say the overall proformance Is outstanding

Besser als Original (das sind die originale Zündkerzen, nur viel günstiger) und das freut mich.

Llegaron en buenas condiciones (la porcelana del aislante es delicada)

No complaints.

Smooth car ride after replacing these along with variable valve timing in Toyota avalon. "Check engine light never appeared again"
