Category: Filters and engine bay accessories


Two jobs in one box: the MPI Automotive PFPV645DPK pairs a fuel pre-filter with a ProVent oil catch can, listed to fit the 2020-on Mazda BT-50 and Isuzu D-Max. It's a combined fuel-cleanliness and crankcase-breather kit for the engine bay, not an exhaust upgrade.
The PFPV645DPK bundles two separate engine-bay protections. The fuel side adds a secondary water-separating pre-filter ahead of the factory unit, trapping water and fine debris before it reaches the high-pressure injection system — useful on Australian diesel where fuel quality varies. The ProVent side is an oil catch can that pulls oil mist and moisture out of the crankcase breather so it doesn't recirculate and coat the intake. Together they target the two most common diesel longevity headaches in one fitment.
The current-shape D-Max and its BT-50 twin share the same driveline, which is why this kit lists across both. From 2020 these utes do a lot of towing and touring kilometres, and that's exactly the duty cycle where fuel contamination and intake fouling show up. Buying the fuel filter and catch can together as a matched kit is usually tidier than sourcing and plumbing them separately.
It's listed to fit the 2020-on Mazda BT-50 and Isuzu D-Max. Confirm your build date and variant with the workshop before ordering — the platform had running changes, and we'd rather verify the mounting points on your truck than rely on feed data alone.
Oak Flats Muffler Men fits these combo kits in-house across the Illawarra. It's bracketry, hose routing and plumbing the two units into the fuel and breather lines — no exhaust work. We mount both so the filter bowl and catch can drain stay serviceable, then check clearances. Both are service items, so we'll flag a sensible check interval when you collect the vehicle. It's priced at the listed catalogue RRP.
