Overview

Sikky Manufacturing Firewall Fittings

Sikky Manufacturing firewall fittings are specialized, high-quality components designed primarily for engine swaps to manage tight clearances at the firewall for A/C and heater core lines. Machined from billet aluminum, these fittings allow for secure, leak-free routing of air conditioning and coolant lines in cramped engine bays. They're available in a variety of sizes.

Additional details:

* CNC-machined billet aluminum fittings are designed to adapt aftermarket or GM A/C hoses directly to the factory firewall/evaporator core on platforms like Nissan 240SX, Scion FR-S/BRZ, and BMWs
* They solve clearance issues during engine swaps, such as when an LS engine leaves less than 2.5 in. between the evaporator core and cylinder heads
* Designed to make plumbing swaps a direct-fit process rather than a custom fabrication job
