Anyone ever put a K&N filter into a VW?

Was considering trying it out - thanks

It's never been done.

I have and it destroyed the MAF within in a very short space of time, the MAF was probably on the way out anyway - K&N are a bit old hat now there are far better options out there like ITG.

Pure waste of money, unless you are going full hat with ECU/engine upgrades.

If its just a cone filter your putting in, expect a possible decrease in torque if you adjust the intake manifold length/volume. This length/volume is very important on the inlet manifold with non-turbo systems with the engines air intake pulse waves.

You'd be better off with go faster stripes.

Or a short shifter kit.

+1 with the go faster stripes,underated
Wash and wax bonnet too will add at least 10hp

What’s with the smarmy comments? It’s a legitimate question.

Although it would help if you told us which model/engine VW and perhaps also what type of K&N filter you are looking at? .. Open cone filter? Enclosed Panel filter?

I had an enclosed RamAir panel filter on my A4 TDI and it made a nice difference.

It was a foam filter with slightly larger surface area and car felt smoohter and more free revving, particularly as it approached the redline.

I’d say it contributed to increased perofrmance too.

Would suggest you look at RamAir and ITG filters, not just K&N.

It's called having a sense of humour,seems like it's hard to come by in this day and age

Google is full of information on k and n filters

Personally i would just stick to a good OEM filter
That's just my own opinion

I use to buy these free flowing filter systems years back when I was younger, made my old 1.3 lancer I had years ago sound like a Subaru, did absolutely nothing in terms of power though. They might benefit a turbo charged engine, I may fit one to my Octavia RS at a later stage as I plan to map the car at some stage.

K&N filters are really crappy things to put into any car. Allow loads of dust and grit and abrasive crap to get right into the engine's internals, without *any* benefit from a power point of view. If you can see pinholes of light through a filter when it's held up to the light, then you'll get dust particles big enough to cause damage to be passed into the engine.

The pressure drop across a proper OEM filter is barely measurable at a tiny amount of a single percentage point of atmospheric pressure - effectively zero for all practical purposes. This means that the filter has less effect on the airflow than e.g. a bend in the pipe somewhere between the throttle and intake valve. Changing out the OEM filter for a "free-flowing" filter means you get no effect whatsoever on the engine's air usage, and a much decreased filtering of incoming air.

By all means if you want the engine internals to be destroyed over time - especially in a daily driver, then throw money away with a non-OEM filter. Otherwise be sensible and use OEM all of the time..

By K&N filter do you mean a regular filter, just K&N brand?




Or a cone filter?

I've been using non oem filters in performance enignes for years and doing decent mileage with no ill effects, apart from the crappy K&N one that killed my MAF. My current car has an ITG/Revo filter in it, my last performance car had an ITG and the one before that had a Jetex after the K&N.

Assuming the OP has a 2018 1.0 TSI Golf, are there any benefits to the filter alone?

Depends on if at the top end of the power band if the car is more limited by the intake or the exhaust. Assuming tsi or tdi, i you were deleting cat dpf etc. and remapping then a competition air filter would add to the mix. A cone filter on a turbo stock car will just change the induction noise. Unless the old filter is blocked you wont get a performace increase. FI engine especially diesel are always limited by the exhaust restriction and not the intake.

It'll sound slightly.... slightly, more whooshy maybe. Feel and hear all of that 110/115bhp, rarrrrrr.

Here's a K&N filter in a VW

Admittedly in the boot, but still in a VW...

OP, I was getting an engine built and when I arrived with a K&N to put on the new Webber's, the engine builder threw it in the bin and told me to get an ITG filter.

However, this was on a proper engine being built with lots of upgrades and the standard airbox couldn't get enough air. For a standard engine I wouldn't bother.

I put a K&N enclosed cone filter in my naturally aspirated car. It looks nice, sounds nice and will likely last the remaining life of the car with a bit of occasional maintenance. What harm?

I don't want to make my car faster, I just want it to feel faster. That way I can have more enjoyment without having to do anything illegal or risky.
