Comments by "JackTannehillPromoter" (@njsongwriter) on "How to change Toyota Spark Plugs on 4 cylinder engines" video.

It's been a long time since I changed spark plugs so I watched this video a couple times and then changed the plugs on our 2009 RAV4. The vehicle has just over 70,000 miles on it but since it's a 2009 model and thus about 12½ years old, I figured it might be a good idea. Everything went as smooth as silk. No trouble getting the old ones out or the new ones in. I put in the same Iridium type of plugs that the vehicle had in it as OEM, Denso SK16HR11 3417 Iridium Long Life. Torque specs I found said 18 ft.lbs. for the plugs and 7 ft.lbs for the bolts on the coils. The mpg has been lower now than it was last year. I'm hoping the new plugs will help. However, the decrease in fuel economy may be due to installing wider tires with a higher rolling resistance. Thanks AMD for this video.

@TheCarCareNut Hmmm, I was wondering about that. We have a 2009 RAV4 with less than 54,000 miles on it. It only had 18,646 on it when we bought it in March 2019. I have no idea if they were replaced at the ten year mark. Since it's been running fine, I'll wait for a warm spring day to take out one of the plugs to see if it looks like it was factory installed. Thanks to the information in your video.

@grambangla1445 Your owner's manual should list the recommended plugs for both Denso or NGK. To be sure ask the person at the Toyota dealership parts counter if the recommended plug in your owner's manual has been superseded.

@andersonrodriguez8258 Our vehicle has 53,750 miles. So far I've done three drain and fills on the transmission fluid. The reason being is that I have an ATF temperature gauge (Scan Gauge 2) and I know it runs hot in the summer.
