Keep Your Coyote Cool

Fat Fender Garage Coyote H-Pipe Bulkhead Adapter

Your Coyote swap runs perfect – until you turn off the heater and watch that passenger side head climb into the danger zone. We've seen it happen too many times. Coolant stops flowing where it needs to go, temperatures spike, and suddenly you're dealing with limp mode when you should be enjoying the drive.

Why Every Coyote Needs an H-Pipe

Here's the problem: when your heater's off, coolant flow to the passenger side head gets restricted. That head starts running hot while the other stays cool, and your ECU throws the truck into protection mode. Not exactly the performance you swapped in a Coyote for.

We've used H-Pipe solutions in every single Coyote swap we build because they work. This isn't just good practice – it's essential insurance for your engine's longevity.

Precision-Machined Solution

Our Billet Aluminum H-Pipe Bulkhead Adapter mounts directly to your truck's firewall with the precision fit you expect. CNC-machined from solid aluminum, available in raw machined or black anodized finish. This isn't a band-aid fix – it's engineered cooling flow that keeps both heads happy, heater on or off.
