Works well
Fits perfectly. For the price of the price it is tough to beat and hopefully will get enough life out of it.

***Trouble shooting a Misfire***
Overall the parts work, noticed the tabs on the hoses are tougher than OEM and may break or become brittle due to the heat of an Engine bay. This PCV is comparable to OEM, I checked the exposed plunger, o-ring and component are all similar to OEM. Bolted on with no issues. I Replaced this component and hoses due to severe Misfires on a 12' Jetta GLI. Car had flashing CEL and EPC with severe misfires. My TS steps included Replacing plugs (NGK 2667) & coils (Autozone), drivable but still had a misfire on all cyl (No more flashing CEL), re-gapped plugs to .027 improved but still had a CEL. Bought Bosch coils (0221604115) improved. Removed and cleaned plugs, continuous misfires may foul new plugs. Observed a leak through the PCV diaphragm vent hole, new unit does not after install, all remaining misfires resolved, no CEL 1000 miles since corrective action. This PCV valve may not last as long as an OEM but it sure works.

Price is good. Fit is not.
These parts, while very close to original, are off enough to make things difficult. Primarily, the o- rings were too thick and required any insane amount of pressure to connect. I even had to reuse the old o-ring on one fitting, and reuse a complete end from another old hose. The nipple on one fitting was molded about 5 degrees off, which made installation very difficult and put undue strain on the pipe. Overall, I wish I would have spent a little more on higher end aftermarket pieces, or even OEM. UPDATE: Seller, GWA auto parts, did a great job of remedying my issues. They took the time to contact me, figure out the issue to current future issues with the parts, offered a partial credit, and were polite and professional the whole way through.

The Hose Ends Rotate
In the end, these parts fit my 2002 E46 perfect. At first however, I thought one of the hose ends was off by 180 degrees. I was pushing/pulling with so much force to get them lined up that I thought I was going to snap the parts. They’re not as flexible as they look. Finally after about 20-mins of messing around, the end of one of the hose fittings actually rotated. They’re so stiff that they look and feel like they’re formed from one pieces, but that’s not true. So if you need to, carefully try to rotate the hose ends, they’ll be stiff, but they’ll rotate. I would even spray WD-40 on them next time. I gave this product a 5-star because in the end my car is running great and the parts fit fine at an awesome price. However, If I could, I would give the engineers at BMW a zero star for the design and ease of replacement.

Poor quality
I bought this kit as I was replacing my starter in my e46 and it’s one of those “while you’re in there” jobs. Install was somewhat of a pain. Car started idling really roughly after getting everything back together. Didn’t think about it too much because it’s my second car. Fast forward a couple months and this rough idle is bothering the hell out of me. The car had quite a few other issues so I assumed it was one of those. After further investigation, this crappy line that came in this kit had cracked on both ends. I ended up replacing it with fuel line and the rough idle vanished. I should have known better than to get a random kit off Amazon. For what it’s worth, I hear more hissing under the hood which is no doubt another one of these garbage lines leaking.

Rear hose didn’t fit. Different connector type.
Rear hose was a square clip on my car. Found clip on this part. With the low price it was still worthwhile to get the whole thing and reuse my rear hose which was not leaking. This part did fix my lean misfire issue.

耐久性は?
02後期46の325です。嵌合部が少しキツい。インマニ外して作業したら問題無いかも…。純正も欠品出てるし、値段的にもセットは有り難い。オイルレベルゲージのチューブのところのゴムキャップは付属してませんでした。
