Kyostar Turbo Inlet Elbow Silicone Air Intake Hose Pipe For VW MK7 Golf GTI R S3 A3 EA888 (a set)

Nice build, have to work really hard the pcv connector to make it fit ,is not right , the hose comes long have to be trimmed to fit amd due to be oversized is in contact with the brake fluid container bringing engine vibrations to my gas pedal.

Quality is good. Metal Intake with silicone tubing.Intake is wider than OEM. Definitely increased air intake to turbo.The silicon pipe initially touched brake reservoir and felt a vibration at the gas pedal, which resolved on repositioning.They could improve the angle and fit a little more.The side port on the metal turbo intake for connector was a mismatch, it is wider and longer than OEM. I had to force the connector in and concerned it may crack soon. Wish I had sanded it before connecting.I would definitely buy it again.

Alright, there are a couple of things to touch on to install.1. The paint on the PCV is heavy, both on the outside, AND the inside. I used chemical stripper on the outside after reading the reviews, if I had time I would've done the inside instead of sanding.2. Lube all the O-rings. I had no problem with the supplied o-ring with a little bit of vac grease on it.3. Remove the PCV hose and install it before you put the elbow on. There's no way to get enough leverage for it to properly seat while it's installed.4. I had to trim about 3/4 of an inch from the elbow side. This prevented the silicone hose from developing a kink, and can be done with a razor (be careful!)Overall, it's not a bad part. It's probably the same as the name brand ones just painted completely instead of the contact points being raw aluminum. The welds are alright, it's definitely not a $30/hour professional doing them, but they were all complete on mine. Once I figured out what I was doing wrong, and felt embarrassed for a few minutes, it probably took an honest 20 minutes to install. As warning, it is pretty close to my master cylinder which made getting the hose on a little tough. The clamps are finicky, but decent. Performance wise.. it feels a little stronger, think switching from thin soled shoes to winter boots kind of increase in throttle response. There is more induction noise, which was welcome.

Doesn't fit without modification. Turbo inlet pipe and pcv hose don't fit. The welds on the inside near pcv outlet were terrible. Turbo inlet hose is to long to fit with oem air box and oem inlet pipe, but could be an okay piece for a short ram cone style open intake. 3 stars on the silicone hose. 1 on the inlet pipe. If you're not willing to spend time to custom fit either of these pieces avoid purchase. They are not direct fit. I had hoped they fit, and just be kind of okay especially for the price, but the pipe is absolutely junk.

If you have an IS20 or smaller turbo. It causes a major restriction and causes wastegate duty to skyrocket if you are using it for an IS38 or Hybrid turbo. Yes, this will give you all the turbo noises. My wife’s Q3 and when my A3 was stock it made the turbo sound crazy loud. If that is what you are looking for, this may be a good purchase. If you are looking for performance, this is not the right option. Yes, it looks similar to name brands but for whatever reason it does not work like name brands. I say this all based on datalogs and extensive testing, not on hunch. I believe the bottleneck it caused was that at high boost levels, the silicone starts to suck in and causes restriction. The turbo inlet pipe is better than stock but not better than the name brands. The PCV inlet is just slightly too large making it almost impossible for the pcv hose to attach. I had to grind the inlet down to be able to forcefully push it on. Again, this is priced significantly lower than similar looking products just know that it isn’t necessarily comparable.TLDR; if you are looking for turbo spool noise only, this is definitely for you. If you are planning on increasing performance, buy once, cry once and choose a name brand.

I removed the O-rings and test fit the size and placement of the elbow. On my 2019 IS20 turbo. Its fitment was good. I removed the elbow and lubed the O-rings and channels they sit in. I made sure it went in evenly and popped right in to place, rotated and locked. If you have issues, remove the 2nd O-ring and it will fit. Mine did! look at the pictures. The silicone tube was straight forward. I was leery to buy, but the price for both was great to pass. So, I expected issues but, I had none. After installation my car had Smooth acceleration and a responsive petal.

I bought this unit out of curiosity for the price. The issue is the design isn't 100% accurate and the PCV hose to the turbo inlet could not fit. Reading other reviews I tried grinding it down, but no matter what I did I could not get it to fit. I will be buying another unit from a reputable company.

The turbo inlet pipe PCV valve hose fitting is around 1mm larger in diameter than the stock piece, had to remove quite a bit of material to get it to fit. The intake hose was approx 1" too long and I had to trim a few times for correct fitment. Other than that they are great pieces for the money and work as expected, but plan to spend more time on install due to possible modification needed to fit.
