BMW Engine Parts for BMW 5 Series E61 (2006-2010)

Transform your N54-powered BMW with the Turner Motorsport B58 Ignition Coil Conversion Kit—the ultimate solution for ignition system reliability and performance. Designed to eliminate the notorious misfires and power loss caused by factory OE pencil-style ignition coils, this kit is a game-changer for stock and modified vehicles alike. Whether you're chasing more power or improved drivability, the B58 ignition coils deliver up to 2.3x more spark energy, unleashing the full potential of your engine.

Why upgrade? The answer is simple: B58 ignition coils outperform all other ignition upgrades on the market with unparalleled spark energy and reliability. Ideal for high-performance builds or daily drivers, this kit eliminates common ignition problems while supporting increased power demands from software tunes like MHD or BM3. Plus, with the included plug-and-play wiring harness and proprietary boots, installation is seamless—no cutting or splicing is required.

Features:

Up to 2.3x More Spark Energy: Maximizes overall performance, offering sufficient output for heavily modified engines.
Plug-and-Play Installation: Includes custom brackets, wiring harnesses, and boots designed for factory mounting locations—no modifications needed.
DME Compatibility: Compatible with factory engine management software for hassle-free integration.

Due to weak plastic construction, the factory plastic crankcase ventilation breather hose is known to fail. After years of exposure to piping-hot engine bay temperatures and chemical-laden oil vapors, the corrugated plastic tubing can crack, crumble, or fail altogether.

We set out to bulletproof your N52 CCV system with a durable silicone breather hose, designed to provide a comprehensive upgrade and permanent replacement for the factory plastic hose. By replacing the flimsy, heat-hardened OEM plastic hose with a four-ply fluorosilicone hose, you'll experience peace of mind knowing your N52 is free from the inevitable return of oil leaks, vacuum leaks, and drivability concerns that would have been.

This breather hose is found at the front of the engine, and is used to connect the oil separator to the valve cover. It replaces OEM part number 11157522931.

Features:

Silicone construction ensures a durable replacement that is sure to outlast OE plastic
Designed as a direct replacement for the factory breather hose
Retains heating function and OE electrical connector
Design:

Four-ply wire-reinforced fluorosilicone hose is designed to resist degradation due to exposure to oil vapors
O-rings are pre-installed in OE connectors for a lasting seal
Includes pre-installed zinc-coated hose clamps for durability and corrosion resistance
Product Development:

Our Silicone CCV Hose Upgrade was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modelling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

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.

2006-2007 E60 530i 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' N52B30O0 engine in the 530i. 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. 

E60 530i Stage 1 Engine Upgrade includes:
aFe Cold Air Intake (filter, heat shield, intake tube)
