6 Best Remote Oil Filter Relocation Kits For Tight Engine Bays

There is nothing more frustrating than staring at a cramped, sweltering engine bay and realizing the oil filter is completely inaccessible for a quick trail-side change. When you are miles from pavement, a simple maintenance task shouldn’t require a professional shop’s worth of specialty tools just to reach a spinning canister. Investing in a reliable relocation kit transforms a nightmare job into a straightforward routine, ensuring the vehicle remains trail-ready regardless of space constraints.

Mishimoto Universal Kit: Best Overall Pick

The Mishimoto Universal Kit stands out for its high-quality construction and versatility, making it the gold standard for most off-road builds. It features a rugged, anodized aluminum mounting block that holds up well against the vibration and debris common in backcountry driving. The included fittings are high-flow, which is critical for maintaining consistent oil pressure across varying engine temperatures.

This kit is ideal for the weekend warrior or the long-haul overland traveler who prioritizes reliability over raw, track-only specs. Its universal design means it fits a wide variety of chassis, provided there is enough frame rail or engine bay real estate to anchor the mount. If the goal is a “set it and forget it” solution that balances performance with ease of installation, this is the definitive choice.

Derale Premium Relocation Kit: Best Budget

Budget-conscious builders often face the dilemma of choosing between safety and cost, but the Derale Premium Relocation Kit bridges that gap effectively. While it lacks the flashy finish of high-end billet options, its cast aluminum housing is robust and functional. It provides a straightforward path to easier filter access without breaking the bank for a simple overlanding rig.

This kit is perfectly suited for older 4x4s or budget project vehicles where the focus is on utility rather than aesthetics. It includes all the necessary hardware for a basic install, though it is wise to inspect the included hose quality for high-heat environments. For those just starting to modify a vehicle for remote travel, this is a dependable entry point.

Trans-Dapt Dual Filter System: Best Cooling

When dealing with heavy towing or sustained, low-speed high-torque climbing, oil temperatures can skyrocket. The Trans-Dapt Dual Filter System addresses this by doubling the filtration capacity and effectively increasing the total oil volume in the system. The added surface area of two filters—or one filter and an integrated cooler—helps manage heat better than a single-filter setup.

This system is recommended for heavy-duty overlanding rigs or trucks that frequently traverse steep, high-elevation terrain. The sheer size of the dual-filter mount requires a significant amount of mounting space, so map out the installation location carefully before committing. If engine temperature management is a primary concern for the next expedition, the trade-off in space is well worth the cooling benefit.

Moroso Billet Aluminum Mount: Best for Track

The Moroso Billet Aluminum Mount is built for high-performance applications where failure is not an option. CNC-machined from a solid block of aluminum, this mount is significantly stronger and more heat-resistant than standard cast units. It is the preferred choice for high-horsepower engines or vehicles pushed to their limits in demanding, high-impact environments.

Because of its precision engineering, this mount is best for those who prioritize structural integrity above all else. It is an excellent investment for dedicated trail rigs that see frequent, heavy-duty abuse where standard mounts might fatigue. If the vehicle is built for serious competition or rigorous, high-stress adventure, this is the component that won’t let you down.

Canton Racing Remote Filter: Most Durable

Canton Racing is synonymous with endurance, and their remote filter mounts are built to survive the harshest conditions. These units feature thick, durable construction and O-ring seals that prevent leaks even after thousands of miles of washboard roads. It is the kind of gear that feels substantial the moment it is pulled from the box.

This is the right choice for the remote traveler who spends weeks off the grid and cannot risk a seal failure or housing crack. It provides peace of mind that a cheaper, lighter unit simply cannot match during a remote expedition. While it comes at a higher price point, the longevity of a Canton mount makes it a cost-effective choice for long-term ownership.

Earl’s Performance Relocation: Best Compact

Tight engine bays are a common reality in modern mid-sized trucks and modified Jeeps, often leaving no room for a large filter mount. The Earl’s Performance Relocation kit features a slim, low-profile design that squeezes into spaces other kits simply cannot reach. Its compact footprint does not sacrifice fluid flow, making it a masterclass in efficient engineering.

If you are struggling to find a mounting spot near the radiator or frame rail, this kit is the most likely solution. It is perfect for modern engine swaps or compact setups where every square inch of space is already occupied by turbo piping or suspension components. When space is the primary constraint, Earl’s provides the most elegant solution available.

Why Relocate Your Oil Filter for Trail Use

Relocating an oil filter is not just about convenience; it is about essential maintenance accessibility in the field. When a filter is tucked behind a subframe or near a scalding exhaust manifold, changing it becomes a hazardous ordeal that often gets skipped. A remote kit brings the filter to a clear, open area, ensuring that a quick oil change can be performed even with minimal tools.

Moreover, a relocated filter is less likely to be punctured by trail debris or high-centering events. By moving the filter away from low, vulnerable areas, the risk of a catastrophic oil loss event decreases significantly. This simple modification turns a complex service task into a five-minute job, which is a major advantage during multi-day expeditions.

Routing Hoses to Avoid Exhaust Heat and Snags

Proper hose routing is just as critical as the quality of the mount itself. Keep lines away from hot exhaust headers and manifolds, as extreme temperatures will degrade rubber hoses and cause them to weep or burst. Use thermal sleeving or heat-reflective tape on any section of the hose that passes near a heat source.

Ensure that all lines are secured with P-clamps to prevent chafing against sharp metal edges or suspension components. Always account for full suspension articulation during the routing process; if a hose is stretched tight at ride height, it will likely snap when the suspension droops or compresses. A well-routed line is a safe line, so take the extra time to ensure there is slack and protection at every pivot point.

How to Choose the Right Line Size and Thread

Matching the correct line size to the engine’s oil system is vital for maintaining proper pressure. Most standard remote kits use -8AN or -10AN sizing, which provides sufficient flow for the vast majority of consumer engines. Using an undersized line can create a restriction, starving the engine of oil, while an oversized line might lead to excessive pressure drops.

Regarding threads, check the specific filter and block requirements, as these vary wildly between manufacturers and vehicle platforms. NPT threads require sealant, while AN and JIC fittings rely on a metal-to-metal flare seat. Ensure all adapters are high-quality to prevent thread galling or stripped ports, as these are the most common points of failure in a relocation setup.

Priming and Maintaining Your Remote Filter

A remote filter installation introduces a longer path for oil to travel, which can lead to a dry start if not properly addressed. Always pre-fill the new oil filter with fresh oil before mounting it to the relocation block. This significantly reduces the time it takes for oil pressure to build upon the first startup after service.

Periodically inspect the entire system for signs of weeping or looseness, especially after a rough trip. Check the tightness of the fittings and ensure the mount remains solid on its bracket. A quick visual inspection before heading out for a long weekend can prevent a minor leak from becoming a major trail-side headache.

By moving the filter to a more accessible and protected location, you ensure that engine health remains a priority rather than a chore. Whether you choose the robust reliability of a Canton mount or the compact efficiency of an Earl’s kit, the investment pays off in both ease of service and vehicle longevity. Get your gear sorted, keep the lines clean, and enjoy the confidence that comes with a well-maintained rig on your next great adventure.
