Nitrous Express .054 R/T Single JetThe NX HP Jets are manufactured on CNC equipment, and are guaranteed to be within . 0005 of specified jet size. In recent testing, using the same jet size, HP jets out flowed the competition by 35%! That's right 35% more flow through the same orifice, how you ask? The HP jet was designed to be more than just a hole in a piece of brass; its contoured inlet and multi stepped outlet allow turbulence free flow with no restrictions. Certificate of Origin

I ordered this Engine Coolant Hose (part #11537545890) for my 2006 BMW 330xi as part of a comprehensive cooling system overhaul. Along with this hose, I had my mechanic replace the thermostat, water pump, radiator, expansion tank, and all other related hoses. This hose fit exactly as expected—no issues during installation. It’s been three weeks since the job was completed, and everything is performing flawlessly. No leaks, no warning lights, and the engine temperature remains stable under all driving conditions. Although this is not a genuine OEM part, the quality appears solid and it matched up perfectly with the original in terms of length, shape, and connector alignment. For anyone looking to refresh their aging BMW’s cooling system, this hose is a reliable and cost-effective option. Just be sure to verify the part number for compatibility before purchasing. Highly recommended if you’re doing preventive maintenance or replacing a failed hose as part of a larger cooling system repair.
