Thanks. Another good website for parts.
I have no problem with rubber stuff it should do the job fine. I think I have re-evaluated and decided since I think the MAF is 3.5" and the TB is 4" I am going to go with 3.5" pipe and a 4"-3.5" 90* reducing bend to the TB. I still need to measure the MAF, but I think it's 3.5".
I think this is the most informational thread on CAI's yet!

 

Glad I could help. The CAI's I build for the TBSS's start off 4" at the TB, and then are 3.5" the rest of the way. I use the 4"-3.5" rubber 90 found on that site.

 

Good info. Thanks

 

why do you reduce it to 3.5, because of the maf? i remember my brute force was full 4 inches and shaved 1.2 seconds off my old 05 silvy with a 5.3. it cost a lot so im gonnaa make one for my SS. im not saying the fact is was 4 inchs shaved that time lol. but more or less whats your reasoning?

 

No reason to go to 3.5", I found that both the MAF and TB are 4". So you can go 4" all the way. After I put on my TBSS intake I ended up getting an Airaid tube for a nnbs and made it reach my existing airbox. It is 4 inches on both ends.

 

Wow, another old thread...there's been a few of these this week I guess old threads mean that folks are using the search feature

 

Hay i suggest using the K&N 63 series Im using it in my 06 GMC sierra 1500

Yeah, no use starting this topic all over again when we've got all those great photos. I was looking at chromeintakes on ebay - thought I'd check it out here first.

 

where can i buy a gm performance intake for a 05 gmc wit 5.3

 

Check Scoggin Dickey (SDPC, sponsor, link to the right >>>), if they're a no go, I'm sure that you can get it from your local dealership...
