AEM's Digitial Wideband UEGO kit is one of the best widebands for the money. Its not only extremely accurate but far more reliable than other kits like innovative or zeitronix. This wideband has a gauge which includes the brain for the system and fits in all 52mm vw/audi pods, including but not limited to 42dd, column pods, vdo lower dash pods, vent gauge kits and TT center vent gauge kits. This gauge is the most important gauge you can have in your car besides a boost gauge! Order before March 1, 2010 and get it at our sale price of $205 shipped anywhere in the continental US.
