If you're looking to swap out that factory cast thermostat housing, the Precision Works B-Series D-Series Thermostat Housing is a solid choice. Trust me, it's not just another shiny part to throw on your ride—this piece is built for performance and durability.
As someone who's spent countless hours tinkering under the hood, I can tell you that this billet housing is a game changer. Made from billet 6061 aluminum, it’s not just lightweight but also tough as nails. The precision CNC machining means it fits like a glove, and you won't have to worry about leaks or fitment issues. It's a direct bolt-on replacement, so you can get it installed without any hassle.
One of the standout features is the 1.25" radiator hose fitting—standard, so you won't have to hunt down any weird adapters. And if you're thinking about upgrading your cooling system, there's an optional 16AN fitting that you can use. Plus, there’s a 1/8 NPT port with a plug, perfect for adding an accessory or a temp gauge if you want to keep an eye on things.
Now, let’s talk fitment. This housing is designed specifically for Honda B-Series and D-Series engines, so if you’re rocking one of those, you’re in luck. Every product that comes out of PLM is something we’d use on our own cars, and this thermostat housing is no exception. We put it through rigorous quality control, making sure it meets our standards before it ever hits the market.
In short, if you're serious about your build and want a thermostat housing that’s reliable and well-crafted, this is the way to go. It’s not just about looks; it’s about performance and peace of mind.
