Rampage Fabrication 4″ Mega MAF


MAF Type


New for 2022 is our 4″ MAF housing. This is the largest and highest flowing MAF housing currently available for the FK8 Civic Type R. These have been independently tested and verified to outflow all other options on the market while still maintaining a perfect idle on stock and aftermarket camshafts. Compatible with both 3″ & 3.5″ G-Series inlets included in our G25/G30 kits as well as PRL’s Race MAF boot for PRL inlet. Designed for use with the PRL HVI airbox only.

For Rampage inlet to 4″ Mega MAF use the PRL Silicone Hose found here.
