ATRACYPART CCV Filter 6.7L ISB — Fit for Ram 2007.5–2022, OE‑Style Direct‑Fit to Reduce Oil Leaks

ATRACYPART CV52001 is a direct-fit crankcase ventilation (CCV) breather filter designed to restore proper crankcase ventilation on 6.7L ISB engines used in Ram, Ford F-Series medium-duty, Freightliner, and Blue Bird applications.

When crankcase ventilation becomes restricted or the housing is worn, engines can show symptoms such as oil leaks, elevated idle speeds, and reduced performance. The CV52001 replacement is built to match OE dimensions and materials so you can swap it into affected 2007.5–2022 Ram trucks and numerous medium-duty and bus platforms without modification. It focuses on removing oil vapor from crankcase gases and preserving engine efficiency under heavy-duty conditions.

How will this CCV filter affect oil leaks and engine idle?

If the original breather element or housing has failed, pressure and oil vapor can migrate past seals and gaskets, creating leaks or erratic idle. Installing the ATRACYPART CV52001 re-establishes controlled ventilation paths and helps normalize crankcase pressure.

• Restores correct ventilation flow to reduce crankcase pressure build-up.
• Captures oil mist to limit oil migration onto engine components.
• Direct-fit design avoids modifications that can introduce new leak paths.

Is this filter compatible with my vehicle and which part numbers does it replace?

The CV52001 matches fitments for 6.7L ISB engines found in many model years and platforms, and it cross-references common OE numbers for straightforward replacement. Check the listed years and models against your VIN or service manual before purchase.

• Fits 2007.5–2022 Ram 2500/3500/4500/5500 with 6.7L ISB engines.
• Also compatible with 2008–2015 Ford F650/F750 and select Freightliner and Blue Bird buses.
• Replaces OEM references: CV52001, 904-418, 68002433AA/AB/AC, 4936636, 5263190, 904418.

What makes the ATRACYPART CV52001 durable and reliable?

Materials and construction are selected to withstand high underhood temperatures and the acidic, oil-laden environment produced by crankcase vapors. The housing uses reinforced polymer and the breather element is engineered to trap oil mist while allowing gas escape.

• Reinforced housing resists heat and impact compared with basic aftermarket housings.
• Media design reduces oil carryover while maintaining flow under load.
• Manufactured to OE-style dimensions for consistent, stress-free installation.

What warranty and support does ATRACYPART provide?

ATRACYPART backs the CV52001 with a two-year limited warranty to cover manufacturing defects and premature failures. If the unit cracks or stops functioning within the warranty period, the brand provides replacement or refund options to keep downtime to a minimum.

• 24-month warranty for replacement or refund on qualifying failures.
• Customer service support to confirm fitment and troubleshoot installation questions.
• Tested for installation reliability to reduce return rates and installation issues.

Who is this for: The CV52001 is aimed at fleet technicians, independent diesel shops, and owner-operators of heavy-duty Ram trucks, medium‑duty F-Series rigs, Freightliner chassis, and Blue Bird buses powered by the 6.7L ISB. It’s particularly useful when symptoms point to a failed crankcase breather—such as visible oil leaks, unusual idle behavior, or a drop in engine responsiveness—and you want an OE-dimension replacement that installs without alterations and offers a backed warranty.
