All Spec Performance Anodized Aluminum Blockguard for Honda D Series Engine: D15 D16 D17 Civic CRX SOHC
Our block guards are CNC milled from aircraft-grade 6061 aluminum right here in the United States.
some are finished in a striking, orange anodized coating for better corrosion resistance.
Using a block guard on your engine turns your open deck into semi-closed deck. They are a must for turbo, NOS, and supercharged applications. Our block guards are machined to be slightly oversized (.500 or 1/2 in) to compensate for the cylinder walk flaw common in open-block designs, and to ensure a watertight seal around each cylinder when pressed into your block. The scalloped design stabilizes the block and provides better temperature control.
Benefits of a block guard:
- Reinforces the block
- Reduces cylinder walk
- Features coolant passages to prevent overheating
- CNC machined from 6061 anodized aluminum
