what are my options on cai's for the big 102mm opening's for my truck.i tried looking around and really didnt find anything. is there any companys that make a bigger cai or would i have to try and fab something up. also i see texas speed sells a 100mm mass air meter. my new motor is gonna be a 408, cam, heads,fast rt 102mm intake,1 7/8 longtubes

 

i have a gm performance on mine and its huge i think 3 1/2 inch

 

Your probably going to have to make something. I just made one for my 90mm intake.

 

I made my own, used siliconeintakes.com for the parts and pieces.

 

u guys have any pics of your intakes u have made?

 

408 i would go SD tune, screw the MAF, i used a 4" silicone 90* then a thin wall pcv pipe, i have taylor sheet metal making me a box to house the filter then a down pipe to force in outside air


allen nelson as a special on ls1truck where he is selling silicone couplers and such

 

PCMforless has a 4 inch intake with a ls7 maf. Its made for a tbss but it would work for a silverado with very little modification.

 

whats a sd tune? and the maf i was just throwing it out there to see if i would net any decent gains

 

SD=Speed Density...MAF's are nice if you do alot of different driving, elevation change,hot/cold weather..etc.. sd/maf each have there own strengths and weakness's, talk to your tuner and get his opinion...LPE has a nice 4" maf as well....

 

102mm is 4.0157480315004 inches..
