Bosch's newest generation injectors are now available in a 725cc, 1000cc and 2200CC high impedance injector!

These are a 48mm long body, shorter than normal injectors. The adaptor tops make them "normal" 60mm length. These have a droplet size comparable to a 600cc Siemens injector and way better spray pattern and atomization than any other injector on the market.

The proper battery comp values are also provided with each set so you can set it up in your computer and have consistent a/f ratios as battery voltage fluctuates. Most other injectors don't offer that information at anything other than 1 voltage level.




Each Precision fuel injector is flow checked, individually scribed, hand selected and then carefully matched to within 1% of each other for optimum performance.
All horsepower ratings are calculated at 90% duty cycle at 43.5 psi upon a BFSC of .50. Compatible with all known aftermarket drivers.




Fuel Injector Clinic Ball & Seat Injectors

Saturated / High Impedance Ball & Seat Injectors
Latest injector technology
Great linearity and short pulse width repeatability
Available in 900cc, 775cc and 650cc

Fuel Injector Clinic injector sets are all precisely flow matched to within less than 2%. Each injector within each set is individually numbered and results for each injector are listed on a detailed flow sheet included with the set. Dynamic flow matching is used only on injector sets where the additional time and cost are justified by the corresponding benefits gained during the tuning process.

Fuel Injector Clinic injectors are flow tested and rated at 43.5psi (3Bar) at 75ºF average fuel temperature using CF-16B calibration fluid.

The superior spray pattern and fuel atomization make these injectors easy to tune and provide great drivability.

Fuel Injector Clinic injectors are set up to fit and include all o-rings needed to fit the factory application for the listed vehicle. For aftermarket or other unusual setups please contact us to make sure you receive injectors that fit properly.

Every injector is covered against failure caused by defects in original manufacture by our 12 month warranty.

Featuring the new "Ultra" Double Digressive Piston (UDDP) with revised shim stacks, this "Ultra" Digressive piston allows for massive amounts of low speed rebound force that helps with driver inputs such as dive, pitch and roll. Furthermore, the rebound force greatly tapers off to provide the driver with "blow off" This helps with large impacts on track helping the vehicle stay settled after hitting curbing at high speeds. After countless hours on the shock dyno and testing on the track, we are proud to offer these high performance coilovers that rival many high end European shocks that cost several thousand dollars more. Due to the ultra digressive nature of this shock absorber, this product is recommended for track use only.

510 Series coilovers are CUSTOM built to order in the USA.

State-of-the-art technology from motor sports for more performance on the road. The separate and independently adjustable rebound- and compression damping allows for an individual suspension setup for different uses and preferences. The unique patented system with its two-stage valves allows a rebound damping adjustment (comfort) and a compression adjustment (driving dynamics) in the low-speed range while the high-speed range which controls the driving safety, is fixed.

- Independently adjustable damping technology -rebound and compression damping
- "Inox-Line" stainless steel technology
- Individual height adjustment
- German TUEV-tested adjustment parameters
- High-quality components for long life
- Comprehensive documentation for ease of use
- Infinitely adjustable rebound damping
- 14- level adjustable compression damping
- Unique, independently functioning damping power adjustment

Compression and Rebound Adjustment:
As far it is vehicle-specifically possible, the rebound damping is adjusted by a spindle at the end of the piston rod. Mainly, the traction phase (rebound) controls car body vibrations and also influences handling and comfort in the low-speed damping range. By using the traction phase adjustment, the vehicle can be adapted to the requirements of the driver. Moreover the driving behavior can be regulated from comfortably rolling to sporty and tense with improved road holding characteristics.

The compression phase adjustment is carried out at the lower end of the shock absorber via our patented multi-purpose valve. The large number of pre-set parameters of this valve allows for a wide range of adjustment for individual use. The unique low-speed compression adjustment significantly distinguishes this technology from any other. In this compression range, the driving behavior of the vehicle is drastically influenced. An increase of the damping power supports the vehicle already during compression and therefore avoids rolling and pitching. The directional stability is significantly improved.
