CCS Oil Catch Can Kit for ND Mazda MX-5 Miata

Description

Direct Fit for the ND Mazda MX-5 Miata

Engineered specifically for the 2016 and later (ND) Mazda MX-5 Miata, this Improved Racing oil catch can kit features a custom mounting bracket that secures to the passenger side strut tower, ensuring a clean, accessible location for easy maintenance and draining.

 

With a superior filtering efficiency of 85-90%, the CCS catch can captures oil vapor from crankcase fumes while adding minimal restriction to the system. This proactive filtration prevents harmful carbon deposits on intake valves, preserving engine health and performance over the long term.

 

An Improved Oil Catch Can

Improved Racing set out to design the best air-oil separating catch can we possibly could. We focused on three simple design goals:

 

1. Maximize efficiency: Separate as much vapor from crankcase blow-by fumes as possible with minimal restriction.
2. Easy to use: The catch can should be simple and enjoyable to use in every aspect including mounting, draining, and cleaning.
3. Durable: Virtually indestructible. Made from high-quality, reliable components. As with any Improved Racing product, nothing will vibrate loose or come apart under racing conditions.

 

The result is the CCS (Catch Can, Sport).

 

 

Highly Efficient Air-Oil Separation

 

The CCS is designed to maximize air-oil separation, achieving a peak efficiency of 85-90%. For comparison, none of the competitors’ catch cans we tested showed a peak efficiency of more than 60%. These results were achieved on our bench testing system at air flow rates of 0-4.0 CFM and vaporized oil injection rates of 0.20-0.30 grams of oil per minute.

 

Tangential Entry Port	Air enters the catch can manifold tangentially, causing it to spin. The centrifugal force of the spinning air forces heavier particles to the outside of the manifold, where they combine into larger droplets.
Stainless Steel Filter	Multiple layers of stainless steel mesh of varying porosities are sintered together to form a single filter. Effective filter rating is 100 microns.  Filter is made from 316 stainless steel and is washable.
Multiple O-Ring Seals	Three internal seals (shown in green) were used to ensure that no dirty air bypasses the filter. This is a major contributor to poor filtering efficiency and a very common problem we found in other catch cans. One primary O-ring seals the top and bottom half of the catch can (shown in red).
Anti-Splash-Back Funnel	The stamped aluminum funnel prevents fluid in the reservoir from splashing back onto the exit port (another common problem found in some catch cans). The funnel features spiral grooves which serve two purposes: They help combine oil droplets so they drain quickly into the reservoir. CFD simulations have shown they help spiral the air, contributing to cyclonic separation.
Bell Mouth Plenum	Extensive R&D went into designing the exit port plenum. The bell mouth shape sheds oil droplets collected on its outer perimeter, preventing fluid from exiting the catch can. The large bell mouth opening slows air velocity before exiting the catch can and reduces the probability of any fluid becoming entrained and exiting the can.
3.5 fl oz (104 ml) Reservoir	The 3.5 fl oz (104 ml) reservoir is more than sufficient for most engines and features an optional remote drain port.

 

No Sight Glass Needed

Improved Racing’s quick-release reservoir is so easy to remove that it eliminates the need for a sight glass. Just push up and twist 1/8th turn to remove the reservoir and look inside. No more fumbling or endless unscrewing to remove the reservoir.

 

No sight glass also means improved durability at higher operating temps. And no more trying to interpret a difficult-to-read sight glass to check your fluid level. Just look inside!

A powerful wave spring keeps the reservoir locked in place. A safety lock clip is also included just in case you want to be absolutely sure the reservoir cannot be removed.

ND Miata Specific Mounting Bracket

Improved Racing’s custom aluminum bracket secures to the EVP control unit mounting location on the passenger side strut tower, providing an easily accessible location for installation and maintenance.

 

We also offer an optional drain kit which allows for remote draining without removing the catch can.

 

Fast & Versatile Mounting Bracket System

We made the mounting bracket easy to use and remove because some engine bays are tight. Remove the can in seconds by unscrewing the green bracket nut. Installing and positioning is just as quick and easy. If you need a little more leverage, just use a 5/8″ or 16mm open end wrench on one of the nut’s lobes.

Positive Lock Safety Clip

The CCS comes with a safety lock clip. It’s peace of mind for crash protection or track events where a positive lock mechanism is required. Push to insert, pull to remove.

 

We also include a lanyard that tethers to any of the mounting bracket screws, so you will never lose your lock clip in your engine bay.

Modular Design & Optional Remote Draining

Improved Racing’s latest generation CCS oil catch cans feature a modular design with a removable bottom cap. The modular design allows for thinner walls, reducing overall mass and overall height while maintaining the same fluid capacity.

 

Don’t worry about leaks! The bottom cap is securely fastened with a retaining clip, so there is no risk of it coming unscrewed and leaking.

 

Tight engine bay? No problem: the bottom cap is easily removed and swapped for an optional cap with a drain port (sold separately) for remote draining.

 

We offer a remote drain kit which includes the replacement bottom cap with drain port, a stainless steel drain valve, hose, and fittings (part number CCS-DKB-06). You can also purchase the bottom cap on its own (part number CCS-26-KIT).

Color Options

The oil catch can is available in Improved Racing Green, or black. Pick the color that fits your style.

 

Extensive Testing

Development of the CCS happened over several years and included ANSYS Fluent CFD simulations, extensive bench tests, and on-vehicle street and track tests. Final prototype testing also included a 9-month beta testing program in collaboration with various road racers, drag racers, and drifters.

 

 

Comparative testing included Improved Racing’s prototypes and several catch cans from leading competitors. We ensured our catch can will beat the competition in filtration performance while maintaining a similar or lower pressure drop. Bench testing focused on maximizing efficiency at peak blow-by air flow rates of 3.7-4.0 CFM, where most other catch cans lack efficiency. The chart below (click to enlarge) shows some of our bench test results. Proprietary information and competitors’ names have been redacted.
