I am doing a 6.0 swap, I want to get a K&N cai but do not know if they will interchange. The block came out of a 03' 6.0 and I have a 00' 5.3 rcsb. The filter elements are they same number, and K&N support is closed till monday, Does any one have any input on this? Is the dimensions different or fitment difference(as far as the tube goes)?

 

When I did my swap I had an 02 5.3 with the K&N for the 5.3 when I swapped the 6.0 everything was fine between a 5.3 and a6.0 the intake manifolds are pretty much identical if it's a truck motor . Now if it's a LS2 then I don't know . But this web site is great sure someone will chime in.

 

I do believe all 4.8/5.3/6.0 fit for 99-06, mines an 06 and I just picked one up off eBay basically new off an 01 and no issues whatsoever, you're good

 

I would say just order it fpr ur make and model year because how it mounts to ur engine compartment it key at the the throttle body it's just a rubber boot

 

The 2003 and the 2000 4.8,5.3, and 6.0 have the same throttle body and intake manifold. It'll fit just fine.

 

run it a 4.8 , 5.3 , 6.0 are about identical when it comes a accesories .....

 

That's good to know. I guess the different part numbers are a way to make us pay more for it. Even though they are probably the same. Thanks to all for a quick response.

 

In theory some are diffrent , the diffrence usually haves to do if you truck comes with e-fans or clutch fan but iether or should work on your , i other words it the same pile of **** on a just fliped upside down

 

I would order an Airraid MIT for the year model of your truck and drop in a performance filter and do the airbox mod. Save yourself a couple hundred bucks!

 

I will look into it. I was thinking of it but didnt know if anyone has done it. Gonna use the search engine.
