Spark plugs

What crap? A couple of hoses on one side? For a modern engine the 4.0 is a piece of cake for a v6 any way. I would go with Densos. On both my 2009 and 2013 the Densos had less gap deterioration at 30k. After the first change at 30k, only to keep emissions warranty valid, I would push it to at least 65 on coppers. With the Densos I had maybe 1 hundredth gap deterioration. You can get Densos online at a lot of places. I got my last set from Amazon. Local auto parts stores may not carry but they can order.

 

+100 percent on the following statement.

 

Did my spark plugs was super easy thank You everyone for the help and advice! Thanks Tacomaworld !!!! The only thing I found weird was both driver side and passenger side had Ngk r spark plugs part number PLFR6A

 

that probably means that they've been changed in the past. how do they look?

 

Means someone changed them before. Those are platinum plugs which usually allow for a longer service interval than the standard plugs.

 

I will take a pic and post

 

Hopefully you guys can tell but they look fine to me

 

yea im no expert, but they don't look bad.

 

Probably could have gone longer on them but oh well they are changed and now I know

 

think about how difficult those two plugs would have been later on! haha

 

Haha true

 

Yeah I tend to think with aluminum heads it is better to do a 30k change interval even if you have iridium or platinum plugs just because of the seizing issue.

 

Didn't even think about that good point

 

Had lots of success in many different Toyotas with Denso twin tips.

 

I picked up a set of Denso plugs today. Asked why there was three Denso and three NGK's and the reply was due to the heads each being assembled in different plants. One plant runs Denso and the other runs NGK's. FWIW. Looking forward to digging into this job!
Cheers

 

I installed Denso plugs into my 07' about 20k ago.

They work great, zero issues!

Keep it simple... and cheap
