Hi, I would like to change my spark plug but have several questions:

 

  • which spark wench to I need 16mm or higher?
  • Some site and my Manual says Denso SK20R11, but when I check on amazon it says that this will not fit my RAV4 2010 model. Now I am confused.

Any ideas?

Better to trust your owner's manual. For further clarification, best to go to the spark plug manufacturer's catalogue for your specific region.

That'll be because Amazon (as an American company) would be looking at the US-spec 2010 Rav4 which runs the 2.5L 2AR engine, not the Australian-spec which still had the 2.4L 2AZ

In short, yes. If you want to double check, then remove a spark plug from your engine.

For comparative pricing purposes, here is an eBay URL.

I was exactly looking at the denso on ebay, but I will check the spark plug inside the engine, maybe I don't need to replace at all.

My Toyota has only done 105.000km.

I understand that in the USA, there are also environmental assessments/charges based upon the level of servicing over the life of a vehicle. This would explain why car manufacturers have introduced longer servicing intervals e.g. 15,000 kms, "sealed for life" transmissions etc. I also love a good conspiracy theory especially those that mirror reality.

Denso iridium long life plug has an estimated/expected life of 80-100,000 mlles. Spark plugs wear and the level of deterioration of performance can be affected by engine variables e.g. running rich or lean, burning oil etc.

Another factor to consider is how long the plug has been fitted to the engine. After so many years, care will need to be exercised removing the plugs particularly from alloy heads.

Just wanted to update this thread ... I finally changed the spark plug SK20R11 (90919-01237) at 118tkm. It was very easy with a spark wench. The old plugs were not too bad, inside it was clean.

Just on the other note: I also changed the coolant, cleaned the throttle body and air sensor, changed engine air filter and cabin filter and of course oil and filter changed as well.

I also washed the engine bay. My rav4 2010 run like a dream now. :)

Good news that you had no dramas removing the existing spark plugs. Hope you remembered to put a small amount of anti-seize lubricant on the spark plug threads. More important when using long life plugs which are not going to be replaced for many years.

Nothing like a good bit of maintenance to keep your vehicle reliable and running smoothly plus the personal satisfaction when DIY goes well.
