About this part
Two interchangeable full-size intake adapters for mounting CA18DET or SR20DET mass-airflow sensors to compatible A'PEXi filters. Includes separate SR20 and CA18 adapter geometries and requires a 3 mm O-ring cord assembled into the seal groove; printed parts only, with filter, sensor, O-ring cord, and hardware not included. Fits S13, S14, and S15 applications with the corresponding MAF and filter interfaces; verify sensor variant, sealing, fastener engagement, intake clearance, and engine-bay heat resistance before use.
