Precision Works Kシリーズ フィラーネックアップグレード（リモートフィラー）

Finally got this installed and the slight curve made routing the hose so much cleaner than the stock setup. The fitment on my K24 housing was spot on with no leaks.

I’ve been putting off this coolant housing swap for weeks, but this remote filler neck made the job way less of a headache than I expected. The straight-to-slight-curve bend clears the firewall perfectly on my K24, and the weld quality is clean enough that I didn’t have to grind anything down before

The slightly curved shape lined up perfectly with my coolant housing, no trimming or fiddling needed. Coolant temps stay steady on long drives now, and the hose routing is way cleaner than the stock setup.
