Parker Performance Custom S550 Mustang O2 Defoulers (Boosted Cars)

***As of 3/28/2024 - This Product is Unavailable.*** 

If you're like us, and you hate that the EPA has eliminated the ability to turn off your CEL in your tunes on your race cars - then you're probably looking for new solutions to overcome this debacle: P0420 CEL dash light and check engine lights. Well we've got a setup here that has been tried, tested, and proven to work in almost every Boosted GT Mustang and many Turbocharged Ecoboost Mustang racecars that we have built for our customers running catless downpipes or longtubes. This defouler kit moves the O2 sensor out of the direct stream, and we've built a filter/spacer combo that has worked great on almost every brand of downpipe &/or longtube header. We pre-build these w/this filter and spacing combo before shipping to our out of state customers, so it's ready to be installed when you get them! As a small performance shop, we install hundreds of downpipes and longtubes a year on our customer's racecars, and we've had about an 85% success rate with this combo here on our boosted customer's racecars. We've tested them on both 93 and E85, we've tested them on Corsa, Stainless Works, Stainless Power, Texas Speed and even the God forsaken 2M longtubes. Price is for either a single (Ecoboost) or for a pair (V6 or GT), with our custom filter/spacer combo. Guaranteed to work, most the time (lol) - sometimes you just need to buy some electrical tape and cover up your gauge cluster I reckon, lol.
