The Anti Lag aka secondary air injection valve is a key part of a proper “rally style” ALS. Please note the ALS valve alone is not enough to correctly control an anti lag system. Below is a quote from the Brewed Motorsports blog explaining how the ALS valve works, we strong recommend reading the full story here: Brewed Anti lag systems explained
Need a full Anti-lag kit? We offer a number of complete Anti-lag Systems for any turbo charged engine.

Secondary air injection:
“Rally style ALS are slightly more complicated, there are also a few different techniques used to get the desired results. I will only be touching on the secondary injection style anti lag as this has proven to work VERY well for our Brewed projects as well as 90% of WRC cars (Toyota, Subaru and Mitsubishi just to name a few). By introducing oxygen and fuel (in the proper mixture) directly into the exhaust manifold pre turbo you can produce combustion similar to the drag style ALS without moving the oxygen through the engine (the throttle plate can be closed or at a very low angle such as lifting off the throttle while cornering) This is the perfect way to lower the amount of stress on the engine/exhaust valves when compared to the drag style ALS as well as provide instant response when reapplying the throttle after lifting. Thanks to the WRC regulations many OEM cars actually came factory with this style of ALS however they were “tuned” off from the factory for the public. Cars such as the Evolution and all all trac celica could simply re map the ECU or use a standalone EMS and activate the OEM ALS!” Brewed Motorsports blog July, 2012
** Please contact us with any questions, keep in mind these are complicated systems that require proper tuning and maintenance. While it is possible to have a secondary air injection system on a street car you will also need all the supporting hardware and ECU/EMS.
