OEM for my 2008 Rav4

I bought these because they are the recommended spark plugs in the manual and the Toyota Maintenance YouTube channel prefers them over NGK plugs. My Rav4 had 105k with the original spark plugs and I figured it was about time as Denso's website lists them for 80-100k. I installed them and was immediately pleased with the smoother ride of the car. The Denso brand is a common OEM for many Toyota components, highly recommended.

Pros
  • Spark Plugs and Wires
Cons
  • There are cons

Former Toyota Dealer Technician

Fits 02 foot LS430. They come with gaps. These are original parts. Toyota factory OEM engines come with NGK spark plugs which can be confusing for some of the reviews posted here.

Please don't come to this condition, the engine doesn't deserve to suffer like this :( Denso is used by both Toyota and Lexus. I'm not a handyman, I'm a former Toyota diagnostician.

Pros
  • Spark Plugs
Cons
  • Fits

After installing the spark plugs, the car runs like new.

My Toyota Camry Hybrid had some engine vibration when stopped at traffic lights and vibration/hum when restarting the engine while accelerating.

The old spark plugs were dirty and the electrodes seemed unusually short. After installing new candles, the car…

Pros
  • Spare parts
Cons
  • The list is getting long.

Perfect fit for 2003 Toyota Camry LE Georgetown, Kentucky, USA

When I started researching what spark plugs I needed for my 2003 Camry LE, I found that the reviews always said how good Denso spark plugs are work in camrys made in japan. All sorts of horror stories have been told about Camry made in USA using different parts. Denso is the main manufacturer of Toyota Camry factory spark plugs. I knew the brand I needed but wanted information with the model number of the fork. I didn't want to change the spark plugs, damage the engine in any way, or put the…

Pros
  • Automotive
Cons
  • Slightly torn
