Block Off Plates & Adapters

Simplify your engine bay and improve reliability with our range of block off plates and adapters. These components are used to seal unused ports, reroute coolant or oil lines, or adapt factory housings for aftermarket setups.

We carry EGR block off plates, coolant and oil block offs, sensor adapters, and billet fittings for Honda, Acura, and other performance platforms. CNC-machined from aluminum or stainless steel, these parts provide a clean, leak-free solution for custom builds, race cars, or emissions deletes (where permitted).

From simple block-off caps to full adapter kits, these upgrades make engine assembly, maintenance, and custom plumbing easier and more reliable.
