Designed to internally be identical to a Celica GTS MAF housing, but without having to hack it to pieces to get it to work with the MR2. OEM MAF sensor positioning and the flow 'vanes' are retained which when incorrect/missing can often cause running and idling issues in 2ZZ swaps. Can also be used on 1ZZ engines for a small power gain Printined in ABS-like resin to a resolution of 0.05mm to ensure smooth contours for good airflow. 76mm inlet and outlet size
