Hello together, I wrote the K&N Typhoon air filter in it… thanks to a few Vid ́s I will be written on by the VW ́lers (!!!) and also the “new” here by Priv.PIN(here also called PM) because of my more/minimum performance NOW here for all my experiences: So I was on a Bosch test bench BEFORE the installation: 132KW on the wheel measured !!! (Hammer good f. series) (yes possibly “scatters” the test bench upwards… But the diff. is of interest) After installation of the Typhoon Kit (and insembled driving 14,000Km): On the wheel:141 KW (190 PS) Same test bench (BOSCH) Same tester same measurement (adjust the halls Temp was equal) z.z. 160KW (218PS) engine output, even if someone thinks that the measurement is too high the diff is also for the question of interest!!! So pure more with My CTR: 11 KW it is the same by the Typehoon filter can not give the F.
