Block Guard (Blockguard) for Honda D17 Series

Block Guards help prevent catastrophic engine failure.
Must have for turbo, NOS and supercharged applications!
Outstanding for NA.

CAD design and CNC milled from 6061 Aluminum

Turns open deck into semi-closed deck

Machined coolant passages promote critical coolant flow especially where the cylinders join

Without these coolant passages, other brand block guards may create destructive hotspots around cylinders

Machined to be slightly oversized to compensate for the cylinder "walk" flaw common in open-block designs
