Tune up

Is this good

 

No. OEM only for plugs and wires.

 

You need dual ground plugs, get the below plugs instead. Wires are good. Can't comment on the coilpacks, I'd go OEM if you can swing it on those. My truck only likes OEM when it comes to electronics and sensors. NGK plugs/wires being the only exception.

You are 100% right the OPs truck needs dual ground plugs. But I think the plugs you linked to are singles.

These are the duals the OP needs.

As far as NGK plug wires. I've been running the NGK wires for a year, with no problem.

 

Mine are duals also, they just use stock photos. I just checked all the reviews to confirm, Ordered them and installed last weekend.

 

Are these the best

 

not sure if you can get better than these Denso
~39k miles on these

 

Stay with Denso OEM part number coils.

 

how often do coils need changed?
i still sport the factory ones

 

I don't know. Mine only have 71,000 miles. Hard to say based on run cycles vs. years. I'm sure somebody here has a recommendation.

 

all i recall at the moment is there may be a CEL trigger if they are bad

 

Link for this is possible I want the best spark plugs

 

How many miles do you have on your truck? You many not need new coils.

Plugs do not need to be expensive to be good. In fact, OEM plugs are reasonably priced. We get a 5% discount with Rock Auto. Let me get you the discount code.

Take a look at plugs for your truck as a price comparison.

seems they may or may not have seriously upcharged me on the parts by $5 eash
if these are the same exact plugs

 

145,000

 

That's not that many miles for coils. I've seen then run longer. The going price for new OEM coils is roughly $85 each.

Are you having a misfire or are you just looking to give the engine a tune up?

I'd do just the spark plugs (dual ground) and NGK wires.

Dealers don't stock the wires any more, most end up using NGK wires now.

I've used NGK wires on the 3.4 tune ups since 2005 with no issues. I still prefer them due to cost and availability.

I've seen injectors fail more often than coils on the 3.4

 

+1

 

Napa sells NGK coil pack rebuild kits. Id do that before I replace, especially with cheapo $10 Amazon coils haha.

 

Good to know.
