Sir, I have Suzuki kei, model 2004,simple efi engine 660 cc.I have a problem of air filter.All the local manufacturers of air filter prepare the air filters of their own dimensions,one 'dimensions does not match the other's dimensions.There is a problem to adjust air filter in the air filter's box.Male - female grooves does not match.Air filter does not closed properly and takes air from outside,so engine does not work properly on CNG.There is same problem in Alto japani 660 cc.
Please help me in this regard
