Hey Everyone,

I have been looking for an answer for this question for a few days now but I can't find one.

I just installed my K&N intake on my 05 sierra 5.3. Evidently you can't use a TBS without making modifications for my make and model. Is this true? I contacted K&N and they don't recommend using a TBS because of the modifications which will void the warranty (which I'm not worried about). Has anyone put a TBS on with a K&N intake? Do you need to do any modifications? Which TBS did you use? And finally, how important is using the stripping around the intake guard?

Thanks for your help!!

 

I am not sure about the K&N, but I have the volant and the tbs and no modification was needed. I assume the K&N is pretty close in design. You should be fine especially with all the room the 05' has with the electric fans. I have the transdapt. And finally, I am not sure what you are talking about with the "striping around the itake guard".

 

Pweiss, its a gasket that goes around the heat shield I guess for added protection for when you close the hood to fill the space, anyways I have one too and to install the gasket cut it at the corners of the shield so it will bend (otherwise it wont) With a little patience and work you can get it to fit

 

^Definately patience!^

 

I have the 6.0 and had to actually cut the intake tube when i put the tbs. I was going to cut the shroud but then measured a lil more and saw that with that extra inch or so wit the tbs the tube would hit the fan. I cut the tube and works fine.

 

Did you notice any difference in performance when you installed teh TBS?

Does

 

Does anyone know if the 05 has more room between the fan than the 04? I don't want to cut the tube if i don't have to.

Is having the spacer even worth it?

 

It was worth it for me. Does feel better and i have noticed a difference in my gas mileage.

 

How long did it take to install with the tube modifications? Did you use a simple hack saw?

 

So, what TBS is the best with my truck (00 5.3) with a K&N 77 intake. I would rather not trim the intake or fan shroud but will I guess if need be. Anyways, most everyone has been good with the trans dapt so I was looking at those. Any input from same year and engine that have done would be awesome. Thanks
