14mm socket to remove the coil pack bolts

 

Stick with Denso or NGK.

Toyota recommends copper plugs for the V6; iridium plugs for the I4. I have iridiums in my V6 and have had no plug related issues. I first tried NGK iridiums; I replaced them with 110K miles and were still running well but the ground electrodes were wearing down. I now have Denson iridium Long Life's.

Edit: it don't matter where you get the plugs.

 

What weight oil are you running?

 

Mobile 1, full synthetic, 0W20...

 

Japanese plugs for Japanese vehicles

Denso or NGK

 

How does the plastic cover come off?

Pretty easy job especially the passenger side, driver side is not bad if you either remove the bracket to the intake manifold or get crafty with some extensions.

 

I've got a 2.7L...

oh well... that changes things. NVM then.

 

2 hours?!?!

 

Thats the time it takes to crack a 12 pack o beer. Drink 2 while you collect tools, drink a beer per cylinder, and then drink 2 more for a post beer celebration.


The lil 4 banger.... maybe a 30 min job, But yes they the i4 take Iridium plugs.

 

How do I get the plastic intake cover off?

 

Your excessive idling not only hurts your gas mileage but also your engine. I would not be shocked if that is a huge contributor if you are idling over an hour on each tank of gas.

Fill the truck up and don't idle it at all this next tank and see what happens.

Short city trips also crash mileage. I get 20mpgs normally if I do all highway. I get 16 driving in the city since I moved and no longer do virtually any highway trips anymore.

This is why I opted not to go for any side hustles that use my truck. They are virtually moneyless jobs when you take out gas and wear and tear on these things out of the pay.

 

FIFY. Duplicate what comes out. Mess with the next owners head if it’s sold....

Edit: Never-mind. Just saw OP has a four banger.

 

I believe toyota uses denso plugs. I put ngks in mine, but either is fine. Just check the gap. Not sure what it is on the 4 cyl. On the v6 the gap is about .044"

Edit: yes you can do it in your driveway. Just clean up around the plug before you pull it so that no dirt falls into the cylinder and be careful not to drop anything in there. Take your time. Don't over tighten the nee plugs. Its a pretty easy job. There are tbreads on here on how to change plugs already.

 

Pretty sure I used 10mm on the coils? Unless the 4 cylinder is different.

 

Didn't see anything said on a dirty air filter. Worth checking and replacing along with the fresh sparkys.

Even with that, all the city driving/idling with A/C is the MPG killer for anything other than hybrids/plug-in electric cars. Chill out on the lead foot and that helps, too. Big difference in my MPG's when I just grandpa the truck around but it takes discipline.

 

I did the NGK (4904)

ILFR6T11 Laser Iridium Spark Plug, it was an instant noticeable improvement.

 

Took me about an hour the first time I did it on my v6, but I'm a mechanic and have lots of tools to help get around the stuff in the way so I barely had to take anything off.
