Go Buy an intake!! You will not be let down

[Last-Call]

Hey everyone, I just installed a K&N intake, with a thotlebody spacer. I am so pissed I waited this long to buy on. It is night a day with response, and you do not need to get into the gas when trying to pass. It feels so much smoother when takinging off from a stop light. The sheets say that the intake will give you 15-18 WHP and the spacer the same. I will be putting the truck on a dyno soon to get the real #'s.

It took a little time and messing around but man is it worth it. I took a few pics fot you guys as well.

Here is the stock mess of intake.....

This is what it look's like when it's all done

These are the holes it sucks air from in the air box

This is where the air has to get though before it makes it into you motor

Now it has so much more area to suck air

This is the TB spacer

These are the little PITA screws you have to remove and replace

Here is the TB spacer in it's new home.

Note, you have to trim the fan shroud and the tip of the fan blades if you run the intake and spacer...Yeah they don't tell you that.


So get off your wallet and buy this stuff, it was the best 265 bucks I have spent on the truck.

What series intake is advisory for the 4.8? Im lookin for one but not sure what to choose.

It is the same thing for the 4.8. K&N '57' cold air intake.

Looks good, my aem brute force intake was a similar install and I love my synthetic oil free filter. You can buy some used ls1 fbody electric fans off ebay or craigslist for around $100, add an efan harness from www.nelsonperformance.com, and reap the benefits of almost 2mpg and 20hp :thumbsup: I'll be adding a throttle body spacer of another form around christmas

These trucks love a little n2o.

How hard was it to wire the new fans?

I'm still waiting on the $1000 for funding but there are plenty of write ups online, nelson provides instructions as well but it really is quite simple

Does the TBS really make a big difference. I just installed a TrueFlow AIT and really haven't noticed a big shift in the mpg, maybe b/c I just do mostly city driving (~85-90%) vs hwy. But last I heard in the 2003 Tahoe the TBS really didn't make a big difference other than adding a "whine" to the engine.

No the only throttle body spacer that helps these trucks have solenoids attached, may help mileage slightly but I don't think they do anything but provide a good location for nitrous.

You can read about them all day, but you have to try one to see the difference. See my 25 MPG thread.
