This is a 5" long silicone hump hose, 4" ID on one end stepping down to 3" ID on the other, with two stainless clamps included. It's built to handle the boost pressure and heat cycling you get on charge air tubing between the turbo, intercooler, and intake manifold on Cummins-powered trucks and Agrale applications.
Silicone over rubber matters here because this spot in the system sees temperature swings that crack cheaper hose in a couple years. The stainless rings inside the hose wall (not just clamps on the outside) keep the shape from collapsing under vacuum or blowing out under boost.
If your old hose is cracked, hardened, or the reinforcement rings inside have separated from the silicone, that's your sign it's time - don't wait for it to split on the road.
Reading the Cross-Reference
F02488S352 and 3356536 both point to the same physical part in the Cummins system. Different catalogs, different eras of part numbering, same hose. That's normal in this business - Cummins has reissued numbers over the years without changing the actual piece.
What you want to verify before you order: ID measurements on both ends (4" to 3" here), overall length (5"), and that your application actually uses a hump-style reducer rather than a straight coupler or an elbow. Charge air plumbing varies enough between engine families that a number match on paper doesn't always mean physical match on your truck.
Surest way to confirm - pull the old hose and check the number stamped or printed on it, or run your engine VIN through your parts channel. Don't guess off memory of what came off a similar truck last year.
Ordering From Us
We keep this one in stock at the Tacoma counter - if you're local and need it same-day, call ahead and we'll have it up front. If you're not local, it ships nationwide and usually moves fast since it's not an oversized item.
Comes with a 6+ month warranty. If it's not right for your application, get it back to us before you cut clamps into it - once it's installed and cut down we can't take it back.
We'd rather spend two minutes on the phone confirming fitment than have you drive back down here with a hose that's a half-inch off. Cheap insurance.

Frequently asked questions
Does F02488S352 fit my Cummins ISX?
Depends on the year and charge air configuration - not all ISX trucks use a 4-to-3 reducer at this spot. Pull your old hose and check the ID's on both ends and the length before ordering, or give us the engine serial number and we'll look it up.
Is 3356536 the same as F02488S352?
Yes, based on our cross-reference they point to the same hose. Cummins has used both numbers depending on the parts catalog or printing run. Confirm by physical measurements or your VIN if you want to be certain before you buy.
Can I use this on non-Cummins engines?
If the ID's match (4" stepping to 3") and the 5" length works for your mounting points, silicone hump hoses aren't picky about brand - they just need to fit the pipe diameters. Agrale uses this same physical part, so other setups with matching dimensions could work too. Measure first.
