Spark Plug Schedule

Posting for myself, I say purchase them directly from the dealer (that's what I do) but I'm sure others will chime in and suggest otherwise (such as Ebay, online store, etc.) you really can't go wrong buying them from the dealership that is unless you give them the incorrect engine info.

Yes you can go in to an auto parts store and request to purchase Denso or NGK's but they just may or may not have the one's specifically for your engine?
The dealership will definitely have what you need.

 

I used to change mine every 60K in my 2008 4.0 V6, so at 175K when I traded the truck I had changed them twice. I always bought the plugs at the dealer, and yes, they needed to be re-gapped. I used to use just a drop of anti sieze on the threads. It's pretty straight forward job as described in a few videos posted on YouTube. There is 'stuff' in the way, but I didn't think it was that bad. Especially after the dealer quoted me a ridiculous price of around $200 to do it. I think the plugs cost around $30 if I remember right? Go for it!

 

I follow the recommendation in the owners manual....I'm simple I guess.

 

Yes

 

Preparing to change the plugs on my 2007 4.0L V6. Ordered NGK Iridium

$44 LFR6AIX-11 - 6 PCSNEW

LFR6AIX-11 because that's what came up for the engine when I searched it on autoanything.com. I looked in the Haynes manual and it suggests

$10 NGK LFR6C11 NGK (7787) LFR6C-11 V-Power Spark Plug, Pack of 1

NGK LFR6C11 OR Denso K20HR-U11, the owners manual suggests the same. Are the NGK plugs that I bought acceptable, just a different version?

 

The owners manual states the gap should be 1.1 mm or 0.043 in.

 

They are good! They are what I am running in mine and were recommended in a thread a few months ago.

 

Obtain the VIN for your truck
Go to Toyota dealer
Give them the VIN and ask for spark plugs for that VIN

 

Get one of these extensions to make life easier. I bought a 6” and needed a 3” extension for it.
