Hey everyone ... i’d like to have a K&N performance air intake system put on my 2017. Golf R. I was told because we gain a few horsepower the car has to be tuned? I just wanted to know has anyone here put a performance air intake system and what has been like since? Thanks a lot

No tune required. Gains are minimal even when tuned.
You will get more noticeable turbo noises though, that's all an aftermarket intake will net you. That and a nicer looking engine bay.

Attached is a graph from K&N showing their gains for a 2015 GTI: http://kandn.com/dynocharts/69-9506_dyno.pdf. This indicates that the car is stock with 9700 miles, so NOT tuned & you car may give different results. You will increase the intake noise with the system also. If this is good enough then go for it.

I'd skip the intake and just do the JB1 or Cobb AP.. or if you must have intake do the AP with Stage1 high boost. I run that profile with my 034 CF intake. Stage1 is night/day difference in power.

I have a hard time believing those numbers. I'd like to see someone here duplicate them.

It's easy to cheat the test. What they would do is open the hood and have a giant industrial fan blowing air onto the front end, so that the filter has maximized cold air as possible.
Who drives with the hood open?

Not worth the cost. I'm not buying the dyno numbers either.

Save the money and buy more beer instead. I've had several cars that had K&N products on them and ultimately there's no difference whatsoever. Really, a dyno gives you raw numbers that are higher than before but unless you drive every day everywhere like a bat out of hell and are measuring times from point A to point B every time, nothing is really gained by these products.
Sure, every horsepower gained is good but 90% of the time you're just driving to the store and, unless you drive like a Grade A a-hole all the time, you're not gonnna realize any actual gains. Spend the money elsewhere.

The power gain will be the same or possibly a tiny bit more by using just a drop-in panel filter like K&N.

I put an Injen intake on mine. The turbo noises are much louder (better) now. Zero noticeable power gain, but oddly enough the fuel economy has improved.

Not odd the car is probably running leaner.

Unless it's calculated MPG it's not accurate.

And unless you top off to the exact same point in the tank/filler pipe every time (i.e. always start with the exact same amount of fuel) your calculations will also be off anyway. Almost impossible to know just how much gas you put in every time.

That's why I fill up at the same place every time and when the pump shuts off run it slowly until it clicks off again. I fill up everyday and be as consistent as possible to check MPG.

Up to 10% ethanol is how gas is sold in my area and is hardly precise. That variation in chemistry will throw off your mpg, also temperature, how much ac you run include defrost, different idle speeds in different temps and humidity. Getting the exact amount of gas in the tank hardly makes your calculations accurate.. but I’m sure we all knew that too.
