Requirements
Why replace it
The factory NA and NB gearbox fill plug has a mild steel square head. Over time the corners round off, and getting it out often means a pipe wrench that damages it further.
The HFM.Parts fill plug is made from 303 stainless steel with a 17mm hex head. The head is slightly longer too, so it’s easier to get a socket on and remove at your next service.

Our Story
We weren't always HFM.Parts; we were Holford Motors. Our brand's identity was forged not in an office, but on the local circuits in the high-stress world of competitive drifting. Our ultimate testbed was our Nissan S14 Drift car, driven by champion Luke Fink. Pushing that car to its limits exposed a crucial truth: achieving genuine, repeatable performance meant relying on components that simply weren't available affordably on the market.
The HFM.Parts brand was born
We made the commitment to design and manufacture the uncompromising, high-quality performance parts that we, as competitive racers, demanded ourselves. Every component you see is a solution conceived, tested, and proven by us. When you choose HFM.Parts, you are investing in components engineered by racers, for racers, ensuring your vehicle delivers its maximum performance potential.
