Most Power / MPG for the $

Why not just get the Airaid jr that gives you the tube and filter for the stock box, and they have an option for a dry filter?

You can do that too, I just like the AFE filters after using them for years. Didnt know airaid was offering dry filters now.

Agreed, assuming he has iridium plugs, but I would change them at 80k and check them at 50k. If not, I would change them every 20k with NGK TR55's gapped at .055". Cheap insurance. I change my fuel filter every 40k, but the NNBS might be an in-tank, don't remember. All of this is just IMHO.

The wife's old Hoe (2004) had 120,000 on stock plugs. But with a your mods and engine work($$$$) I would switch plugs, filters and fluids often too!

Ahh ok

Does anyone know if the fuel filter is in the tank?

Just because it turns on doesn't mean ignore regular maintenance. Please pull one of her plugs and snap a picture of it for me. If there is half an electrode left, I'll be impressed. I replaced my mom's 2002 at 60k miles and it idled smoother, accelerated quicker and picked up 1 mpg.

But I don't sell spark plugs nor have any vested interest in anyone's regular maintenance, I am just trying to help with sharing from personal experience and what I have learned along the way.

No I believe you! The 2004 is gone now, but the Chevy manual stated that the plugs were good for 100,000.

Ben, I had that exact setup on the 08 Tahoe I had. I spent like ~$500 on all of that and it was WELL worth it. Do it!

I'm waiting on the MIT and the K&N drop in filter to get here I ordered them last week.

Now I'm trying to decide on the magnaflow muffler or borla. I'll probably do something different for a exhaust tip. I'm certainly not a fan of dual tips or the look of the volant tips.

Obviously the tune will be last but theres a couple other things I want to do performance wise first.

I wish my truck was a 2009... but unfortunately its not. Its only got 70K miles on it though.

I had the magnaflow 12589 on the Tahoe and it has a great tone. Nice and deep and not too loud. I highly recommend that one if you decide to go with magnaflow.

 

[Ben]

Ill prolly do that. I want to run a slightly larger pipe leaving the muffler. I think it would look better.

I would go with Magnaflow. I've had both and will not run Borla again. 18" case will give you a deep, mellow rumble and loud WOT, and a 22" will be quiet around town and sound great when you get on the gas. Go with the 22" if you plan to do catless headers later.

Haha, good deal

And my mom's plugs didn't actually look that bad, but it sure ran better after they were changed.
