SUBARU Diesel Particulate Filter DPF

SUBARU DPF / Diesel Particulate Filter

The Subaru Diesel Particulate Filter (DPF) is a vital component designed to reduce harmful soot emissions from diesel engines, ensuring cleaner air and compliance with environmental standards. Specifically engineered for Subaru diesel models like the Forester and Outback, this filter traps and accumulates soot particles during normal driving. Over time, the DPF undergoes a regeneration process, burning off the accumulated soot to maintain optimal engine performance and fuel efficiency. Proper maintenance of the DPF is crucial to avoid common issues such as warning lights, decreased...

Find your Diesel Particulate Filter / DPF by specifying your model
  • Forester

    The Diesel Particulate Filter (DPF) in the Subaru Forester is a crucial emission control device designed to capture and burn off soot particles produced by the diesel engine. Integral to meeting Euro 4 and Euro 5 standards, the DPF ensures that your Forester reduces harmful emissions, contributing to environmental protection and regulatory compliance. This system operates primarily through two phases: filtering particulate matter during vehicle operation and an automatic regeneration process that incinerates accumulated soot at high temperatures, restoring filter efficiency.

    Commonly fitted on Subaru Forester models with the 2.0L diesel engine (EE20) produced between 2013 and 2018, the DPF requires proper vehicle use to avoid premature clogging. Short urban trips at low speeds often hinder passive regeneration, leading to frequent forced regen cycles or warning lights. Left unchecked, this can impact engine performance, fuel economy, and may cause costly damage to components such as the turbocharger or EGR valve.

    Maintaining the DPF system involves regular monitoring and professional cleaning services, which safely restore filter functionality at a fraction of replacement costs. Krosfou offers high-quality, durable replacement DPFs manufactured in stainless steel with advanced technology, backed by a 3-year warranty to ensure reliability. Whether through cleaning or replacement, proper DPF care is essential for keeping your Subaru Forester diesel running clean, efficient, and compliant with evolving emission standards.

  • Impreza

    The Subaru Impreza Diesel Particulate Filter (DPF) is a vital component designed to reduce harmful emissions from diesel engines, specifically for the 2.0 D engine models produced between 2009 and 2016 under Euro 5 standards. This advanced system combines a catalytic converter with a particulate filter to capture and burn soot and fine particles, ensuring cleaner exhaust gases and compliance with environmental regulations. Proper maintenance, including regular preventive cleaning, helps avoid costly downtime and keeps your Subaru's engine performing at its best by preventing premature clogging of the DPF.

    Whether you drive a Subaru Impreza from the GR or GH generation, or more recent models, a well-functioning DPF is essential for efficient exhaust management and optimal engine power. If the DPF warning light appears on your dashboard, it signals the need for inspection to prevent increased pollution and engine issues. Replacement and cleaning tutorials are readily available, making it easier to maintain this critical filter. Additionally, while technically possible, DPF removal involves legal and environmental considerations that should be carefully weighed.

    Krosfou provides high-quality, durable DPFs manufactured with cutting-edge technology and stainless steel construction, offering excellent reliability and performance. With certified quality and strong environmental benefits, Krosfou’s Subaru Impreza DPF solutions ensure your vehicle runs clean and efficiently, supporting sustainable driving while minimizing costs and downtime.

  • Legacy

    The Diesel Particulate Filter (DPF) is an essential pollution control device fitted on modern Subaru Legacy diesel models, such as the 2.0D variants (EE20Z engine, Euro 4/5). Its primary role is to trap fine soot particles produced during combustion, drastically reducing harmful emissions from the exhaust system. Over time, DPFs can become clogged with soot and non-combustible ash, particularly when frequent short trips or low engine speeds prevent proper regeneration cycles. This can result in DPF warning lights, increased fuel consumption, and potential engine or turbocharger damage if left unchecked.

    Subaru Legacy diesel models equipped with DPF include the Legacy IV and V series 2.0 D 4WD variants, with filters compliant with Euro 4 and Euro 5 standards. Compatible with several Subaru models such as Forester, Outback, and XV, these filters require regular monitoring and maintenance to maintain optimal engine performance and emission control. Professional cleaning services offer cost-effective solutions to restore filter efficiency without replacement, while new DPF units ensure guaranteed compliance with original equipment standards. DIY guides and diagnostic tools also support owners in addressing common DPF issues related to soot accumulation, pressure sensors, and regeneration cycles.

    Choosing a reliable, high-quality DPF from trusted manufacturers like Krosfou guarantees durability and full adherence to European emission regulations. Whether tackling DPF clogging or simply needing replacement components, ensuring correct fitment and technical support can help maintain your Subaru Legacy’s engine health and environmental performance efficiently and sustainably.

  • Outback 5 (V) (2014-2019)

    The Subaru Outback Diesel Particulate Filter (DPF) for the 5th generation Outback (BR, 2010-2014) is a crucial component in reducing harmful emissions from its diesel engine. Designed to meet Euro 5 standards, the DPF captures up to 99% of soot particles produced during combustion, significantly cutting down carcinogenic particulate emissions. Positioned within the exhaust system after the catalytic converter and before the silencer, this filter is made from durable ceramic materials such as cordierite or silicon carbide, structured with microscopic channels that trap soot while allowing exhaust gases to flow.

    Functionality involves both passive and active regeneration processes to maintain efficiency—passive regeneration occurs at high engine loads by burning off soot naturally, while active regeneration is electronically controlled to clean the filter when soot levels are excessive. Proper maintenance of your Subaru Outback’s DPF is essential to avoid issues like increased fuel consumption, power loss, and engine warning lights. Techniques include driving at higher speeds for sustained periods or using cleaning additives to manage soot and ash buildup safely.

    Krosfou offers top-quality, brand-new DPFs specifically engineered for the Subaru Outback 2.0D AWD (EE20Z) with guarantees ensuring reliability and long-term performance. Their filters provide an excellent balance of effective emission control and engine performance support, helping you maintain your vehicle’s compliance and environmental responsibility while ensuring smooth driving experiences.

  • Trezia (2010-2016)

    The Subaru Trezia diesel particulate filter (DPF) is a crucial component designed to reduce harmful emissions from diesel engines, specifically tailored for the Subaru Trezia 1.4D 90 hp model. Positioned within the exhaust system between the catalytic converter and silencer, the DPF effectively traps up to 99% of fine soot particles, significantly lowering the vehicle’s environmental impact. Made primarily from durable cordierite ceramic, this high-performance filter features a structure of thousands of microscopic channels that capture particulate matter while allowing exhaust gases to flow smoothly.

    To maintain optimum functionality, the Subaru Trezia DPF undergoes automatic regeneration cycles that burn off accumulated soot. These include passive regeneration during high-speed motorway driving and active regeneration controlled by the engine management system during urban or low-load conditions. Proper maintenance, such as regular forced regeneration via diagnostic tools or hydrogen carbon cleaning, is essential for preventing clogging that could lead to performance issues like increased fuel consumption or power loss.

    Krosfou offers premium quality Subaru Trezia diesel particulate filters manufactured with advanced stainless steel and ceramic technology to ensure durability and compliance with European emission standards. Their DPFs guarantee reliable performance, helping vehicle owners reduce pollution while protecting engine health and enhancing longevity.
