Modern emission regulations require a closed PCV/Breather system for cleaner operation. However, inefficient oil particle capture can lead to excessive oil vapor ingestion, causing carbon buildup, reduced performance, and fuel economy. ECS Tuning's updated ECS Baffled Oil Catch Can, now with an easy-to-empty 1/4" drain fitting, is engineered to collect toxic blow-by gases, minimize carbon deposits, and reduce oil contamination within engine oil. Recirculating oil vapor ensures emissions compliance without venting to the atmosphere.

• Key Features:
• Highly Efficient Oil Separator: Strategically positioned 4 chamber baffle system maximizes oil/air separation and minimizes oil droplets in the intake tract.
• Integrated Dipstick: Knurled and black anodized oil dipstick simplifies oil volume inspection.
• Reservoir: Available in 6oz or 8oz capacity with a 1/4" NPT drain plug fitting.
• Serviceable: Easily removable baffle plates and drain plug for cleaning.
• Easy/Customizable Installation: Combine with the ECS Universal Bracket Kit for simplified installation and adjustable mounting locations.
• Leak-Free Fittings: Machined -10AN ORB (O-Ring Boss) fittings available for secure connections (fittings sold separately).

For performance-driven enthusiasts seeking weight savings and premium quality, ECS Titanium Wheel Bolts are the ultimate choice. These bolts, designed for both BMW and MINI vehicles, offer a significant weight reduction of 50% compared to steel bolts of the same size. Crafted from annealed titanium alloy using CNC machining, these bolts ensure reduced rotational mass on the vehicle. Tested to meet class 10.9 fastener proof load requirements, they exhibit exceptional durability and resilience.

Product Benefits:

• 50% lighter than steel bolts, reducing rotational mass
• CNC'd from annealed titanium alloy for high strength
• Tested to class 10.9 fastener proof load requirements for durability
• Conical seat design ensures proper fitment
• Ideal for performance-oriented enthusiasts seeking weight savings

*Note: When installing wheel spacers, add the size of the spacer to the length of the OE wheel bolt for proper fitment (ex. 26mm Length OE Wheel Bolt + 15mm Wheel Spacer = Requires a 41mm Length Bolt).

Drastically improve the looks of your vehicle while improving your vehicle's handling characteristics and/or easily adjust your wheel fitment to allow for the proper clearance when installing parts such as new wheels, big brake kits, or lowering suspension components.Interference from components such as shocks, springs, or control arms are a common issue when installing wheel that are not a direct OE size replacement. By moving your wheels a few millimeters each, you can give yourself enough clearance for proper wheel fitment and give your car a wider stance in the process.

ECS Tuning wheel spacers are constructed of high quality 6061-T6 aircraft grade aluminum and are specifically designed by in-house engineers and cnc machined to exact standards, ensuring the best fitment possible. By carefully measuring the OEM wheel hubs and bore dimensions, these spacers mount with minimal clearance to prevent any vibration, retaining the stock-like vibration free operation. 

This kit includes wheel bolts that are lab tested to meet or exceed ISO 898 class 10.9 mechanical and physical properties to ensure perfect fastening of the wheel to the hub with no issues or potential to snap under aggressive driving conditions.

ECS Tuning is a performance and genuine parts provider that designs their ECS Tuning branded aftermarket automotive parts in-house to ensure the highest quality and affordability possible. Every part's design is subjected to a rigorous test fit and stress test period to guarantee proper fitment and continued reliability for years to come.
