Some of the biggest issues when owning a BMW can come from cooling system components. Even through years of improvement, the same failure is seen with the plastic fittings and adapters from years of hot to cold temperature fluctuation. The N54 engine sees failure at the plastic cylinder head outlet adapter connecting the cylinder head to the thermostat hose. The stock plastic adapter simply shears off at the end of the barbed fitting, creating a massive coolant leak.

Features:

  • 【Perfect Replacement】The OE hose fitting is a known weak spot in the coolant system as it commonly cracks and leaks. Our upgraded water hose fitting is to replace the stock fitting with aluminum that will never wear out, crack or leak.
  • 【Aircraft-grade 6061 Aluminum】Made of 6061 Billet Aluminum instead of plastic,which is durable and wear-resistant. 
  • 【Smooth Flow】There are no sharp corners on this fitting so that the coolant will not be disrupted as it passes through.
  • 【Max Coolant Flow】Our aluminum fitting has a larger diameter than the OEM part which improves the coolant flow and cooling performance.
  • 【Easy to Install】Direct fitment with no modification, easy installation.

  • Type: Water Hose Fitting

Good Quality 👍

Easy install, perfect if shipping more faster

It's easy to install and use, but the shipment arrived a week late. Other than that, it's a solid product.

Great solution

Excellent solution to stop the plastic fitting from failing over time and damaging your engine.

Readily available, fast delivery

This is a clear upgrade over the low-quality OEM plastic part. It should be considered a maintenance item, as your stock plastic piece WILL fail eventually.

Perfect replacement

This part saved me the trouble of buying a whole hose for my 330i. The factory hose flange is part of the hose, and it was broken. The factory clamp was also broken. The hose is about an inch shorter, but it looks good. If you're replacing a leaking oil filter housing, you'll want to get one of these. But the price is amazing!

Better than original a lot

So far, so good. The OEM parts were more worn than I expected, so Im glad I replaced them. They perform as intended. Fit and finish look flawless. Ive only run a few hundred miles over the summer, but the hose clamps are holding tight, installed perfectly, and no leaks. The O-rings long-term condition remains to be seen, but so far, so good.

You should replace earlier

The stock plastic flange failed and stranded me roadside. Replaced it easily. The aluminum version is far superior to the original plastic. If your car still has the OEM plastic part, I recommend swapping it before it breaks.

Review from BMW Technician!!

I rarely endorse aftermarket parts specially for BMW's but this is an exception. This aluminum fitting eliminates the possibility of it ever breaking again and the part fits and works perfectly.

Add grease to seal and housing to get item to seat correctly.

Great item. Easy install. Just put a thin coat of grease on the seal and put a thin coat of grease on the lip of the housing. Line it up, and the part will seat. Hold part. Install bolts tighten down with hand.

This part fit my n54 very well

The oring was tight but it did go in when I added oil. I removed it again and the oring did not tear so it does work.
