Owner reviews for air filter

I just put in the K&N drop in air filter and I notice surprisingly large throttle response. It almost makes the ascent feel like a lighter vehicle.

I did a oil change, fuel and air filter at this point.

Fitted k&n drop in last night, mk7GTI, 100% feel a difference, very subtle but it’s there. I suppose time will tell if there’s a downside. Ever so slight difference in response, coasts slightly further in gear without foot on gas. Drove it a lot today and felt the fuel economy might be a tiny bit better too, but I’ve no solid proof whatsoever, but I drive it a lot so I know it very well. All of which would make sense from a less restrictive filter.

I CLEANED and oiled the K&N filter my truck had when I bought it. It went from 14 mpg regularly, to almost 18 regularly.

I used a K&N oil free washable filter for years without any issues. I only recently took it out when I moved to a CAI. I washed it about every 10K miles. Takes about ten minutes and I would just do it in the evening so it had all night to dry.

I just cleaned mine at 45k. Wasn’t very dirty, but followed instructions to a tee. Just used the cleaner, let it sit for a couple hours, rinsed with water, low pressure. Then I let it dry completely (like 3 days - I put in the original filter I still had as a temp). Once dried, oiled it enough to let it soak in as directed. Made sure nothing dripped. Popped it in and good to go for another 2 years.

last night everything was all normal, K&N filter in the stock airbox with one side cut out. sounded pretty nice. ive had this setup for a little over 6 Months .. Today i start my car and head off to work as normal. and i notice its being very very quiet (almost stock sounding)

In my passator, I had a KnN right on the maf, it felt awesome but when the engine gets hot, the hood thermo liner didn't let any heat escape, to the car felt like an 8v

I had one in mine for a little while before reading around and watching videos on these. I noticed my engine made a louder ticking noise with it and I saw absolutely no gain let alone one that would offset the cost.

I've been an OE filter fan since about 1999. Then I had an '87 Carrera and built a killer NA motor, Euro pistons, SC cams, ARP bolts everywhere, Ti bits, SSI headers, custom muffler, a custom Autothority chip, and a big fat K&N air filter. I was detailing the car for a concourse and removed the K&N. The intake runner was covered in gritty dust/dirt.
