4" intake setups, please post pics or give advice!

[Tom Tom Turbo]

I've got my new 4" inlet turbo and will be running a speed density tune, but I'm somewhat puzzled about how all of this is going to fit together. First, with the Precision SLIC and a 4" tube coming from the air filter to the turbo, that's a very tight fit, right?

Next, how are you guys keeping the A/C lines from rubbing and smashing the air filter? My K&N is 14" overall length, 4" outlet, and tapers from 6" diameter down to 5.25" at the end. Am I better off running some flex tubing and placing the filter down under the headlight?

Give me some ideas here fellas!

made my own fits great

here is the one I made

I made a 4" flex tube from the turbo to filter which was way up by the headlight, 9 x 4" though. The easiest thing to do is just use one of the TB.com vendors (TR custom parts comes to mind first) for a 4" maf pipe:

4" INLET Pipes

or, use zip ties or bend a custom aluminum bar/bracket to hold flex tube off the alternator. I had success using these guys for 4" tubing: Flex Hose Ducting, Dust Hose, Fume Hose, Oil Mist, High Temp Hose

that just looks hokie pokie

I understand we have some vendors that make this piece, but I'm not going to drop that kind of money on something that I can make to fit my setup perfectly for about half the price.

The rjc 4" inlet pipe is sweet. It lines up really well with the cold air intake from buickgn.

Here is some pics of various ones we have done over the years. Plain or polished aluminum or chrome plated steel. Made to match up with our cold air kits.

For $30 it is what it is. I was going for a semi stock appearing, but it is too glossy for me, actually I pulled it back out to run my 3" maf and a stock Kirban replacement hose since I have yet to upgrade to xfi/sd. FYI- The inside of the flex tube is built for flow for industrial vaccum systems, it's pretty smooth over the spiral and it won't collapse, won't melt, won't rattle- I needed bolt cutters to cut the spiral binding.

Mark, I'm not discounting the quality of your setup, I've had two of yours in the past, but with the 14" long filter I'm running and using the air dam scoop, I need to put this filter in a certain area to keep the A/C lines from rubbing it, so I don't think I can use your setup.

Has a buddy do the TIG on this but it cost me $10 and solved the immediate problem of rubbing the A/C lines.

Other then the Bung for the IAT it's just 3" Intercooler tubing.

hello: I don't know about a 4" MAFP but I've heard it's a tight fit especially with the IAC and you need an angled adapter to make it work. I'll be experimenting soon with parts got from (frozen boost) to make a 3.5" MAFP and there you'll find pcs. for a 4" also. From pipe to silicon adapters.
good luck

Here is mine full throttle set up with integral Maf Sensor.

I moved the charcoal canister and installed an elbow and pull air from outside the engine compartment.

You guys see any gains with the 4" MAF?

If you run a big turbo with a 4" inlet you would'nt what to put a 3" pipe that would be a big restricton,if you what to make big power you have go big pipes.

hello: I've never heard of anyone going thru with what it would take to compare pipe dia. or MAF sensors. The larger the more flow and that's got to mean more power. I'm going with a 3.5" and it should be enough with what I'll ever do. IMO just upgrading to a newer MAF sensor will help all around. I'll see as that's what I'm a gonna do.
