anybody make their own custom air intake tube between air filter box and throttle body?

on my 2000 5.3 the rubber grommet on the tb measures around 4" id, it then needs to make a sharp 90deg bend

(can't stick out more then 41/2" or will rub on fan blades). then need around a foot of straight pipe to join into factory rubber bellows. any ideas on what product to use? white pvc, regular exhaust piping?

I would shy away from PVC if I were U but I have seen it done! Its not flexible and if for some reason it shifted enough to get hit by the fan or got brittle or something such as an accident cracked it....pieces may get sucked into the intake?

 

I've seen it happen on Turbo Diesels and they will mess a turbo pretty bad but its just a RARE possibility Self aspirated gasoline engines! If you could come up with something that when impacted it dents or gives would be better.

I use exhaust tips for my intake tube. Every time I give it some gas, it goes WOOOO-WOOOOOOO!

well i think the only way im going to make something fit will be to remove engine driven fan and clutch

and replace it with electric fans. that will give me about 8 inches of room for the 90 deg bend. reading lots of posts and am leading towards some ls1 car fan kits. i know i have the 28 inch rad and a tranny cooler to worry about, maybe go and check autowreckers on days off.

 

oh i also have some msd 8.5 super conductor wires coming tomorrow, will post a review vs stock

i installed the msd wires last weekend, and have not noticed a difference in idle smoothness, power or fuel econ.

yet. somewhat disappointed.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
