Ensure proper sealing when installing the turbos on your N54.

Kit includes:

• 16 - ASA M7x39 studs
• 16 - Flange nuts
• All required gaskets and o-rings
• Water pump install hardware
• Replacement vacuum hose
• T-bolt clamps

Helpful hints:

For complete installation instructions, refer to Haynes Service Manual (T#193950).

Both downpipes must be removed to remove either front or rear turbo. Tie rod end may need to be separated from knuckle for clearance. Steering rack may also need to be rotated away from subframe for access. Valve cover heat shield will need to loosened and pushed upward to get clearance for turbo manifold removal.

If studs back out of cylinder head and nuts are seized to studs, replace studs. Thread studs in to head by hand to prevent cross threading. When installing the new studs in the cylinder head, use a high temperature loctite in the cylinder head side, and copper anti-seize on the nut side.

To make more room for access to the front turbo, remove the rubber line running in front of the subframe that attaches to the back of the map thermostat and remove the clip. Cut off the OEM clamp and replace it with a new hose clamp as well.

Complete removal of the water pump is not required. Detach the water pump from the side of the block and push it out of the way to make more room for access to the front turbo. If water pump is unbolted from the block, the aluminum bolts must be replaced.

Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug.

To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new OE quality components, replacing any potential fault points in your ignition system for peak performance!

See kit contents below for a complete list of included components.

*Includes spark plugs that are two steps colder. We recommend these for cars that will be track driven only*

Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.

Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.

From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

N54 HPFP failure is common with BMWs that use this powerplant. Our Packaged by Turner N54 High Pressure Fuel Pump Replacement Kit includes everything you need to replace your N54 HPFP.

Kit includes:

• Genuine BMW Re-manufactured High pressure fuel pump
• Intake manifold gasket sets  
• Throttle body gasket 
• Low pressure fuel sensor 
• High pressure fuel sensor 

2006 E90 325i Stage 1 Performance Package
Peak Power Gain: +29hp / +29ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is a cone filter with a heat-blocking shield around it. The larger surface area of the filter, combined with the heat shield, allow more cool air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

Our flash software is tuned especially for a cold-air intake, maximizing the potential and providing smoother power delivery. We take the stock software and make adjustments for 91 octane (stock software is set around 87). We can get more power and torque, and increase fuel efficiency without affecting driveability or the life of the engine. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

Our software fully maximizes the 'low-output' N52B30 engine in the 325i. Our software has been carefully developed on the dyno and the road to provide optimal power and torque gains at all RPM. We change the fuel, Valvetronic, and VANOS maps as well as revise the factory torque limiters. We have paid particular attention to increasing low and mid-range torque. The stock BMW software is hampered by settings for 87 octane fuel. By re-mapping the engine programming for 91 octane, we can make more power, torque, and improve fuel mileage - all without harm to the engine or affecting driveability. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

There are two ways to install our software: mailing the ECU to us for a reflash or do-it-yourself install with our Turner Flash tool:

Mail-In Reflash - lower upfront cost but additional shipping charges. Minimum downtime of at least three days. We have a 24 hour turnaround on shipping the ECU back to you but factor in transit time. Expert installation of your software at our facility.
Turner Flash DIY tool - higher upfront cost but files are emailed back and forth. No downtime - you can still drive the car while we process your tune. Files are emailed back and forth - your stock file comes to us, a tuned file is returned to you. Easy install via Windows laptop. 

E90 325i Stage 1 Engine Upgrade includes:
aFe Cold Air Intake (filter, heat shield, intake tube)
Turner Motorsport Performance Software Flash
