The enthusiast's choice for over a decade, the Shark Injector's performance is only equaled by its own ease of install! Tune your ECU at the press of a button simply by plugging into the under-dash OBDII diagnostic port, there is no removal of your car's computer; no laptop or cables required. What does the Shark offer?

• Excellent horsepower and torque gains - peak: 18whp/11wtq, max: 22whp/16wtq
• Faster and smoother throttle response

​Turner Motorsport Power Pulleys 
Underdrive Power Pulleys work to 'free up' horsepower. Any accessory that spins from the main drive belt is using up power. That's power that could otherwise be used to move the car. By giving some of that power back to the engine, you can make the car faster! We measured 10.7 whp at 6960 rpm and 8.1 lb-ft of torque at 5550 on a 1995 M3. Race pulleys deliver even more power. 

Another "no-downside" upgrade, we even include a new belt. Total install time for a 3-piece pulley set should be around 1.5 hours. We offer three options in pulleys:
1.) No alternator pulley included - for cars with big amps and powerful stereo systems that need the extra juice.
2.) Street Power Pulleys - our most popular option with no downside!
3.) Race Power Pulleys - delivering 15 "free" horsepower, this set underdrives the water pump, power steering pulley, and alternator for lower temps, less wear, and more power. Not for street use.

Shark Injector Performance software includes:

• Saves your last Sport Mode setting
• Horsepower and torque gains
• Faster and smoother throttle response
• Top speed limiter removed
• Extremely easy to install/uninstall
• Reversible and reusable

Performance software is a must-have upgrade on your E46 M3 and you won't find an easier and better software solution than the Shark Injector. Developed by BMW tuning expert Jim Conforti, this device plugs into the car's diagnostic port and flashes new performance files into your car's engine computer (ECU). There's no removal of the ECU and shipping, no cables, no laptop required - only a battery charger! Installation takes just a few minutes and your engine will perform like never before!

The M3 performance software was developed on the dyno to create maximum power and torque using premium 91+ octane fuel and revising the torque limiters in the ECU. The software makes changes to the ECU's maps and algorithms for fuel injection, ignition timing, VANOS and camshaft movement, and transitional fueling. We modify the maps for part throttle and full throttle so you get better response and more torque at all RPM. Choose between a stock or raised rev limit. The top speed limiter is removed. By fine tuning these maps we've been able to improve the S54 engine beyond what BMW did by making more power and torque and a smoother-running engine.

The Shark Injector plugs into the diagnostic port inside the E46 cabin. With the battery charger supplying power, press the Upgrade button and within minutes the ECU is reflashed with the new performance tune. No other software product on the market comes close to how easy it is to install. You can use the Restore button to re-install the stock BMW software at any time. Detailed instructions are included. Other tuners require you to remove the ECU and ship it to them or use a laptop to read and write a new file. The Shark Injector is ready to install right out of the box! A planned future upgrade will allow you to use the USB port to load different performance files.

E46 M3 Dyno

Power and Torque Gains Stock: 278.2 whp / 235.3 wtrq Sharked: 284.2 whp / 236.9 wtrq Peak Gain 6.0 rear wheel HP and 1.6 rear wheel Torque (note: the max gain (biggest improvement) is 9 rear wheel HP between 7000 and 8000 rpm)

The Sport Mode Memory option will remember if you left the car in Sport Mode or not. When you restart the car it will be in the last setting you used. This is perfect for owners who use Sport Mode all the time. You won't have to remember to press the button each time you start the car. The Sport Mode button functions the same as before so you can turn Sport on/off at any time. The software will remember which one you left it in.

The ECS Exact-fit water line is a perfect upgrade if you're tired of dealing with brittle failure prone parts under your hood. The reinforced fluorosilicone hose has been pre-formed to route the same way your stock line did so you can maintain that clean factory installed appearance. Upgrading the line fitting with a billet aluminum piece eliminates the failure prone plastic fitting giving your cooling system strength.

Included:

Aluminum fitting

• Material: 6061-T6 Aluminum - MIL-A-8625F Type II Class 2 black anodized for superior corrosion resistance and strength
• Single-piece design avoiding additional interfaces that may cause leaks
• Matches OEM style connection to upper coolant hose

Silicone hose

• Material: Black Reinforced Fluorosilicone Lined Coolant Safe Silicone
• Pre-formed hose to ensure OEM style routing and appearance
• Can maintain the use of your stock retaining clips to route the hose in identical locations (due to slight variations in silicone the retainer on the expansion tank may not fit)
• Pressure tested to ensure 2X operating pressures to ensure reliability

A combination of billet fittings and AN lines for an upgraded and serviceable crankcase vent hose. Attaches between the oil separator and the CSL air box.

The factory rubber/plastic hoses become brittle and crack over time. Brittle and cracked hoses can cause multiple vacuum leaks that are impossible to repair without hose replacement. Vacuum leaks can cause many problems including rough running, missing, stalling at idle, and even a no-start condition. The factory hoses offered by BMW are plastic and will yield the same results of becoming brittle and damaged over time.

We have created a full motorsport-style solution with our CSL Crankcase made from machined 6061 billet aluminum with AN-style fittings and nylon fiber braided lines. This is a fully serviceable replacement that will outlast every one of the OEM replacements. Our AN crankcase line can be used to replace the factory brittle hose to ensure your S54 is free from vacuum leaks and performing properly.
