well how big is your inlet from the turbo to the filter element? it should be 3inches mine is.

***Sabri You have a stock GTi-R MAF which is the same size as an SR20DE MAF. The hose connection from the MAF to the turbo inlet is closer to 2.5 rather than 3.0. A T04E turbo has a 3 inlet but the T25/T28 inlet is closer to 2.5.
