Founded in 1966 by Hank Manley, Manley Performance Products began life as Manley Speed Equipment, with a product line that included stainless valves, forged pistons, and several internal engine components.

This is a RACE ONLY product manufactured and sold for installation on vehicles to be used solely for competition purposes, which, once installed, may never be used, or registered or licensed for use upon a public road or highway. If you install this part on your vehicle and use that vehicle on a public road or highway, you will be considered in violation of the Clean Air Act and personally subject to a civil penalty of $4,454.

AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost-effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of an engine. AEM was the first company to release a wideband air/fuel ratio gauge with its Classic Digital Wideband and delivers the fastest-responding wideband air/fuel controller with its patented X-Series wideband technology, which allows you to see AFR changes other controllers may miss. Both wideband air/fuel ratio gauges are 52mm to fit standard gauge pods and include everything you need to install them. Both wideband gauge designs include outputs to transmit AFR data to a logging device or engine management system. If you do not need an air/fuel ratio gauge, the X-Series Inline Controller is ideal for users who only need AFR data for logging, feedback control, and/or transmitting to a dash display. AEM also offers wideband sensors, bungs, and no-weld installation mounts to satisfy the installation needs of everyone from the weekend racer to the professional. When you want the best tune, you need the best air/fuel controllers. Trust AEM, the pioneers of the wideband gauge.

AEM's High Volume Fuel Filter is capable of supporting fuel flow for vehicles up to 500 horsepower. Double O-ring seals deliver superior leak protection and the filter’s 6061 aluminum body provides excellent durability. The standard high-flow filter element is replaceable and available at most auto parts stores so you aren’t stuck if you need to replace it during a race. This unit is a direct-fit replacement for most Honda/Acura applications or used as a floating application on most vehicles.

AEM’s High Flow In-Tank Fuel Pump is designed for high performance naturally aspirated and forced induction EFI vehicles. It delivers reliable performance and high volumes of fuel flow for roughly half the cost of comparable performance fuel pumps.

AEM High Volume fuel rails feature a 1/2-inch fuel bore to support fuel flow for applications up to 1,000 horsepower. This large bore also dampens backpressure pulses created by larger injectors and works perfectly with stock injector sizes.

A Cold Air intake system relocates the filter outside of the engine compartment to deliver the coolest air inlet temperatures possible. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horesepower and torque.

AEM’s V2 intake systems use a patented dual chamber design to produce the most power and torque of any other intake system available—even our own Cold Air systems.

AEM Air Intake Systems are designed to produce massive horsepower and torque gains as well as better engine sound.

AEM Tru-Time Adjustable Camshaft Gears increase horsepower and torque without having to change the camshaft(s) and are must-have items for engines that are milled, forced induction, high compression and/or utilizing aftermarket competition cams. AEM Tru-Time cam gears enable users to match cam timing with their vehicle's tuning state by advancing or retarding the cam profile(s) in one-degree increments via true laser-etched markings. Precision-cut gear teeth ensure no premature wearing of the cam gear's belt surface and AEM's anodizing on the adjustable cam gear's teeth is lab-test proven as the hardest anodizing process on the market.

AEM strut bars are constructed from 1-1/2 inch steel tubing, providing great strength and low weight which gives you a true racing option and a more professional alternative to many hinged or weaker strut bars on the market.
