At Nippon Auto Spares, we’ve specialised in genuine Japanese import engines and OEM parts since 1995. Based in Derby and shipping worldwide, we help drivers, garages, and import specialists source reliable JDM components that simply aren’t available through standard UK channels.

One of the most common questions we hear is: “How do I know which part I actually need?”

The answer usually starts with a symptom, not a part number. Below, we’ve grouped some of our current excess stock by the problems they solve, making it easier to diagnose faults and choose the correct genuine replacement.

Overheating / Warning Lights

If your hybrid Toyota is displaying warning lights, running hotter than usual, or entering reduced-power mode, the issue often lies with inverter cooling.

Toyota Inverter Cooling Water Pump (G9020-28022)

This pump is responsible for keeping the hybrid inverter at a safe operating temperature. When it begins to fail, drivers may notice dashboard warnings, overheating alerts, or inconsistent performance.

A genuine replacement ensures proper cooling and long-term reliability of the hybrid system.

Poor Acceleration / Rough Idle

Hesitation, uneven idling, or sluggish throttle response are classic signs of airflow or internal engine issues.

Mazda Throttle Body Assembly (9B4G-9F991-A)

A failing throttle body can restrict or mismanage airflow into the engine, leading to rough idling and delayed acceleration. Replacing it with an OEM unit restores smooth throttle response and consistent performance.
 

Mazda 6 2.0 Petrol Engine – Engine Code PE

If performance issues persist despite replacing supporting components, internal engine wear may be the root cause. This low-mileage JDM PE engine is fully tested and ideal for full replacements or rebuild projects.
 

Subaru XV 2.0 Petrol Engine – FB20

Loss of power, excessive noise, or oil consumption in Subaru XV models can indicate deeper engine issues. The FB20 engine is known for smooth delivery and reliability when replaced with a quality JDM unit.
 

Knocking / Vibration / Uneven Handling

Unusual knocks, vibrations through the steering wheel, or unstable handling are often linked to worn suspension mounting points.

Toyota Suspension Arm Bush Bracket (52380-28050)

This bracket secures the suspension arm and helps maintain proper alignment. When worn or damaged, it can cause vibration, clunking noises, and uneven tyre wear. A genuine replacement restores ride comfort and handling stability.
 

Windows Not Working

Slow, stuck, or non-responsive electric windows are a common failure on ageing MPVs and imports.

Toyota Estima Left Front Window Regulator

If the window motor runs but the glass doesn’t move smoothly, or doesn’t move at all - the regulator is usually at fault. This OEM regulator restores factory-smooth window operation.
 

Poor Visibility / MOT Failures

Cracked lenses, faulty mirrors, or damaged housings can reduce visibility and result in MOT failures.

Nissan Elgrand Door Mirrors (E51 & E52 Variants)

Damaged or non-functional mirrors compromise safety and are often flagged during inspections. We stock genuine Elgrand mirrors, including high-spec versions with correct wiring and camera support.
 

Nissan Elgrand E51 Facelift Right Headlamp

A cloudy, damaged, or incorrectly aligned headlamp can fail an MOT and severely affect night-time visibility. This OEM facelift headlamp restores proper beam pattern and factory appearance.
 

Mirrors Not Adjusting or Folding

If your mirrors no longer adjust, fold, or respond to controls, the issue may not be the mirror itself.

Nissan Elgrand Mirror Control Switch (27500-1JB2B)

This interior switch controls mirror adjustment and folding. When it fails, mirrors may appear completely unresponsive. Replacing the switch often resolves the issue quickly and cost-effectively.
