Components marketed as “delete kits” for the exhaust gas recirculation (EGR) system on Toyota 22RE engines are available for purchase through online marketplaces. These kits typically consist of block-off plates and associated hardware designed to disable or remove the EGR system. The availability on platforms like Amazon facilitates widespread access to these products for vehicle owners and mechanics.
Disabling or removing the EGR system is pursued for various reasons, including perceived performance gains, simplification of the engine bay, and addressing issues related to a malfunctioning EGR valve. Historically, EGR systems were implemented to reduce NOx emissions by recirculating exhaust gases back into the intake manifold, lowering combustion temperatures. While beneficial for emissions control, some argue that EGR systems can lead to carbon buildup and reduced engine efficiency over time. However, disabling or removing such systems may have legal and environmental consequences, depending on local regulations.
