The caliper sliding bolts are one of the most overlooked wear items in your braking system. Subjected to constant motion and often without adequate lubrication the guide bolts see a lot of wear and tear. Factory BMW caliper guide bolts are very expensive from the dealer - these 304 stainless steel bolts are less than half the price and provide outstanding resistance to corrosion and wear. They are manufacturered with tighter tolerances than the factory bolts too.

Price is per bolt unless noted (2 required per caliper).

The N5X family of engines marked the start of a new era for BMW. The all-new aluminum block powerplants featured a host of technical upgrades, aiding in power output, reliability, and performance. Among these technological advances is an external electronic water pump, which removed load from the engine's accessory drive and allowed for advanced pulse-width-modulated (PWM) control.

From factory, the N52's electronic water pump is limited to a measly 200W output—strong enough for daily driving, but lacking in performance applications. Recognizing this shortcoming, ECS engineers set out to create a high-flow water pump upgrade that doesn't break the bank. Their high-quality adapter wiring harness and bracket allow you to install a 400W N54 water pump without any modification, an effortless, yet effective upgrade that doubles the output of the factory water pump!

By increasing coolant flow capacity, the 400W pump improves heat extraction from the cylinder head and engine block during high-load operation. This added thermal headroom is particularly beneficial for modified engines, sustained aggressive driving, track use, or operation in elevated ambient temperatures where the factory pump can operate near its limits. Improved circulation helps maintain more stable coolant temperatures and reduces the risk of localized hot spots.

Features & Benefits:

Upgrades to the more powerful 400W N54 water pump for increased coolant flow and improved engine cooling efficiency Sealed adaptor harness ensures secure connections and optimal operation under demanding conditions The N54 pump's higher power output offers longer-lasting, more effective cooling compared to the stock N52 pump Design:

40A fused power wire safely handles the increased power demands of the N54 pump, providing consistent and stable performance Sealed and robust construction, designed to withstand heat and moisture, ensuring reliability in even the most challenging environments Plug-and-play compatibility is designed for easy integration with the N52 engine and N54 water pump, minimizing installation time and complexity Kit Contents:

Achieving precise exhaust fitment can be tricky—especially when the exhaust hanger has room to slide. This movement can cause annoying rattles or even lead to contact with the underbody or rear bumper. The ECS Tuning Exhaust Locking Collar offers a simple and effective fix. Designed to clamp securely around the exhaust hanger, this collar keeps everything firmly in place, eliminating unwanted movement.

Crafted from high-strength 6031 billet aluminum and finished in a sleek black anodized coating, it delivers both durability and corrosion resistance. With this collar in place, your exhaust stays exactly where it should—no rattles, no surprises.

Product Design:

Made from precision machined 6061 aluminum Black anodized finish Stainless steel M5 X 0.8mm hardware Installation & Support:

Install the locking collar around your exhaust hanger, position the hanger in place, and snug the locking collar down in place against the hanger! ECS Exhaust Hanger Locking Collars are available for 10mm and 12mm exhaust hangers. Please measure your hangers before ordering. The 10mm locking collar can be found HERE.

If you already have the ECS open cone filter for you N54 car then this is the perfect add-on upgrade for your system to really clean up the engine bay and keep your cone filters much cleaner. When you upgrade to the enlcosed filter kit your filters will be surrounded more more consistent cold air and by protecting the filter from engine bay dirt you are reducing the risk of air flow problems from build up.

The ECS Kohlefaser Luft-Technik (Carbon Fiber Air Technology) intake for the 135/335/535 is a beautifully crafted dual-cone intake with a glossy carbon fiber enclosure. Developed in-house using ECS's chassis dyno and state of the art laser scanning and 3D CAD technology, the N54 carbon airbox is a direct replacement for the stock system. Laser scanning allows ECS to produce a finished product that is a perfect fit to the engine bay. All tubing is also made from carbon fiber with each piece designed for optimal flow. The carbon fiber sandwiches a special heat-blocking fiberglass core, insulating the air box from engine bay heat. All of this combines to produce more power and torque over a wider RPM range - up to 13ft-lbs and 18hp when combined with a Cobb software tune, FMIC, and exhaust. And it looks amazing every time you open the hood.

Features:

• Designed and engineered using CAD technology for optimal flow and fitment
• Stainless steel hardware
• Direct replacement for stock air box; integrates seamlessly with stock intake piping
• Beautiful and functional carbon fiber/e-fiberglass construction
