Nano filters are the way to go

Reviewed By Mark K (Topeka, KS) Reviewed for a 2015 Honda Civic —2/11/2018 8:34 PM

Been using Injen dry filter for long time. Aside from AEM..this is my preference filter. Keeps dirt out of engine and my oil changes show less wear in analysis. Add the nylon pre filter too for xtra filtering. Using this filter on HPS SRI.

Injen SP Series Cold Air Intake Reviews

Great Product on 2016 VW Jetta 1.8TSI

Reviewed By Kyle F (GAINESVILLE, FL) Reviewed for a 2016 Volkswagen Jetta —1/31/2018 5:55 PM

Had to purchase Torx bits (T25 and T30) to finish the job. Directions are for the 2.0 TSI engine, so discrepancies when installing on the 1.8 TSI Gen 3. A friend and I installed in about 2 hours. Afterward, great sound from the engine and noticeable pull in the midrange. Diverter valve is now audible between shifts, which is probably the best feature. Mind the brake reservoir, ensure the turbo inlet pipe is as high as it can be while still secured. Injen makes a great product for this Jetta.
