The MPI Automotive BOL05-B25 is a pack of 25 extractor bolts with a 14mm head, an M10 x 1.5 thread and a 25mm length, listed for the Nissan Patrol, Nissan Navara D22 and Ford Falcon. It's the fastener you use to bolt extractors or manifolds to the head, supplied in bulk.

What is an extractor bolt and why buy a pack?

An extractor bolt clamps the extractor or manifold flange to the cylinder head. They live in a hot, vibration-heavy spot and are routinely replaced rather than reused, because heat-cycled bolts can seize or lose clamp load over time. The BOL05-B25 is a 25-pack of the same bolt — 14mm head, M10 x 1.5 thread, 25mm long — so a workshop or builder doing a full set has spares on hand without ordering them one at a time. There are no performance figures attached to a bolt; the spec that matters is that the head, thread and length match your application.

Will it suit my vehicle?

It's listed for the Nissan Patrol, the Nissan Navara D22 and the Ford Falcon. The dimensions are fixed — 14mm head, M10 x 1.5 thread, 25mm long — so the question is whether your extractor and head use that fastener. Confirm the bolt size against your setup with the workshop before ordering, because feed data covers the listing rather than your exact build.

Is it road legal?

A bolt is hardware, not an emissions or noise component, so it has no bearing on registration status on its own. What matters for compliance is the exhaust system it helps hold together. If you're unsure about your full system, raise it with the workshop.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men uses fasteners like the BOL05-B25 when fitting extractors across the Illawarra. We match the bolt to the flange, clean the threads, and torque evenly so the joint seals against the gasket. If you're supplying your own extractors, bring them in and we'll confirm the bolt spec before fitting.
