Spark Plug Confusion
Decided to change the original spark plugs in my 2008 4Runner we've owned since Feb. 2008 that's clocked 95,150 miles. Not running or idling bad but seems like the mileage is down a little but hard to tell in the summer because 90% of the time it's got a 20.5' bass boat on the back of it. But on our Florida trip last fall it almost always averages 23 mpg @ 72 MPH once we get through the mountains and on flatter ground but was just at 22 mpg. Just a little over due.
Look them up and the OEM plug should be a Denso Spark Plug# K20HR-U11. Okay do a little research and find for about a buck more a plug I find a Denso Spark Plug # PKH20TT which is a double Platinum plug. Cool I'll do that. My local Advanced Aparts has them and I get a discount there.
Here is the confusion. Not mine but it was somebody's. So I start replacing them. Do the left or drivers harder side first just because when changing plugs a long time ago I learned to always do the hardest side first. Just seems to go better. Left or Drivers side plugs were all NGK LFR6C-11. Okay I expected the Denso Spark Plug# K20HR-U11 oh well! So I proceed with the right or passenger side and they are all the Denso Spark Plug# K20HR-U11's. So right bank Denso and left bank NGK's. Who knew!!!
Any how here are the pics of the 95,150 mile plugs. They all gapped right around .055" to .060" just a little out of spec.
