Revitalize your BMW's performance with Eldor ignition coils. Sluggish acceleration, misfires, and rusty terminals may indicate a worn coil. Located on the engine's top, these coils require inspection and replacement every 60,000 miles or as needed. Ensure your ignition system is in optimal condition for peak performance.
Located at the rear of the cylinder head, this essential component controls the central VANOS (variable camshaft timing) valve. Often, these actuators fail due to oil contamination and electrical issues, leading to drivability problems and illuminated check engine lights.
Thankfully, URO Parts offers an affordable, high-quality replacement that functions just like the original factory part.
Features:
Guaranteed Fit: Designed for perfect compatibility with your vehicle. Durable Construction: Made from high-strength materials that resist engine heat and vibration. Precise Manufacturing: Built to OE dimensions for accurate clearances and alignment. Optimal Performance: Matches OE specifications to ensure proper timing at all engine speeds. URO Parts boasts an impressive catalog of over 8,000 premium spare parts, many of which are specifically engineered to replace factory BMW components. With a strong commitment to precision, durability, and value, URO Parts ensures each part meets the highest standards. For reliable and cost-effective replacement components, URO Parts is the go-to choice.

The Precision Raceworks G8x/G2x Stand Alone Auxiliary Fuel System is the highest-performing and most stable low-pressure fuel system on the market! Forget about how things have been done and embrace the benefits of dedicated fueling for your port injection!
Since direct injection came out for BMW, enthusiasts have been adding port injection. With this came the need to upgrade the low-pressure fuel system to keep up. Historically this was done by increasing the output of the main fuel system. Unfortunately, the main fuel pump is controlled using PWM by a factory programmed controller designed to reduce output when target fuel pressure (typically 5 bar) is exceeded, creating a constant battle when pumps are added or upgraded. This limits upgraded fuel pumps from performing to their full potential.
Additionally, the high-pressure pump control system dumps fuel back into the low-pressure system at high pressure low volume resulting in oscillations of the low-pressure fuel system. Because of this, the DI system in the car is required to constantly make corrections to keep target AFR in check.
With this stand-alone low-pressure fuel system dedicated to your port fueling that is a thing of the past! Get rock-solid fuel pressures at any pressure, run fuel pressures that are 1:1 scalable to boost pressure, flow more fuel with dedicated lines, run smaller injectors and still get more fuel than you did with large injectors (allowing for higher resolution), put less demand on the car’s DI system to correct for fluctuations in pressure, even your tuner will be grateful as the system makes tuning of port fueling even easier and more accurate, the list of benefits goes on and on!
