Product Information


Denso Premium Class Iridium Long Life Spark Plug is fast becoming the standard for today's high-tech engines. Employing a revolutionary 360 degrees laser welding process, Denso has created a spark plug unlike anything on the market today. This particular spark plug is designed for durability under the most extreme conditions, thanks to a patented Iridium alloy that is 6 times harder and 8 times stronger than conventional platinum and can handle temperatures in excess of 4,000 degrees Fahrenheit.

  • Features fine-wire iridium center electrode for maximum firing performance and minimum voltage requirements
  • Platinum ground electrode resists gas and electrical erosion and corrosion extending service intervals to 100,000 miles
  • Tapered cut improves firing performance by reducing quenching
  • Withstands higher pressures and temperatures

Founded in 1949, DENSO is a leading aftermarket supplier of innovative, OE-quality products and technologies in the automotive industry.

Best Answer:Hi Brent, There are different kinds of spark plugs and we guarantee fitment based on our vehicle guide and spark plug code. This is an SK16HR11 code. To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.

Iridium Long Life Series Spark Plug, Sold Individually
Oem match for 2010 Toyota Rav 4 4 cylinder engine
This is an OEM match for the factory spark plugs that come with your 4 cylinder 3rd generation Toyota rav 4 (2006-2012). Fits my 2010 perfectly and installation was 20 minutes. Made my engine sound better, reduced vibrations, and improved throttle response. Don't know about mpg as my 4wd 2010 limited never got good mpg. Good inexpensive way to do some diy maintenance on your car.
Purchased on Aug 12, 2015
Bought these to replace the ones in my Camry, with only 21,000mi on them. When I removed the factory plugs I saw they were all various gaps (.037, .038 etc) and some charring. I verified these new plugs had ,044 and installed them. Noticeable difference. Better performance.
