What You're Actually Buying
This is a 90-degree silicone charge air hose, 4 inch inside diameter, with 5 inch legs on both sides of the bend. It's the coupler that runs between your intercooler piping and the intake side (or turbo outlet side, depending on your setup) on the charge air cooler system. Multi-ply silicone construction rated for the heat cycling that boost hoses see - a lot better than stock rubber that goes brittle after a few years of Tacoma winters and Central Valley summers.
Comes with two clamps in the box, so you've got what you need for both ends without making a separate trip for hardware.
This isn't a make/model specific part number - it's a generic dimension replacement. Plenty of Class 8 trucks and some heavy pickups run a 4" ID 90-degree elbow in this exact geometry somewhere in the CAC piping.
Why the Numbers Cross and What to Check Before You Order
F01104S352 is the part as we sell it, and it lines up with the Mishimoto HTSEC90-400-BLUE because both are the same silicone elbow spec: 4" ID, 90-degree bend, 5x5 leg length. Silicone hoses like this cross between brands mostly on dimension, not on a truck-specific casting number - unlike a water pump or a brake drum where you're matching bolt patterns and spline counts.
What actually matters here: ID has to be dead-on 4 inches (not 3.75, not 4.25 - silicone doesn't stretch enough to fake it), the leg lengths need to clear whatever brackets or heat shields are in the way on your truck, and the bend needs to be a true 90, not 45 or 60. If your old hose has any of those different, this one won't seat right no matter what the label says.
Pull the old hose and measure it yourself, or get the size off your CAC piping diagram before you order. Don't just go by "charge air hose" in a catalog - there are 30-degree, 45-degree, straight, and reducer versions that look similar in a photo but won't clamp up right.
Ordering From Us
We keep this in stock at the Tacoma counter - if you're local and your rig is down, call ahead and we'll have it ready, no waiting on a truck from Ohio. If you're not in the area, we ship nationwide and most orders go out same day if you order before early afternoon.
Comes with a 6+ month warranty against defects. Silicone hose failures are rare if it's sized right, but if something's off with the material itself, we'll take care of it.
If you're not sure this is your size, snap a photo of the old hose next to a tape measure and send it over - takes us thirty seconds to confirm ID and leg length before you commit to an order.

Frequently asked questions
Does F01104S352 fit my truck?
Depends on what's actually in your CAC piping, not the make and model. This is a 4" ID, 90-degree, 5x5 leg silicone elbow - if that matches your old hose's dimensions and bend angle, it'll work. Measure the old one or check your service manual's CAC hose spec before ordering, since a lot of trucks run different diameters or leg lengths in the same general area.
Is this the same as the Mishimoto HTSEC90-400-BLUE?
Same dimensions - 4" ID, 90-degree bend, 5x5 legs - so it crosses on spec. Color's different (this one's not blue) and ply count/construction can vary slightly between manufacturers, but functionally it fills the same spot. Confirm your old hose's exact ID and leg length either way, since even a quarter inch off will make it fit sloppy or not seat on the piping.
Do the included clamps work with my factory piping?
The two clamps included are sized for a 4" ID hose over standard CAC piping OD, which covers most setups. If your truck runs an unusual pipe wall thickness or you've got aftermarket intercooler piping with a different OD, check that against the clamp range before assuming - worst case you use your own T-bolts and set these aside.
