The CorkSport EGR Delete Kit is Here!

If you’re looking to help your racing engine stay healthy and clean, read on as we introduce the CorkSport EGR Delete Kit for Mazdaspeed 3, 6, and Mazda CX-7 Turbo.

An exhaust gas recirculation (EGR) system is a very common control system that recirculates some exhaust gases back to the intake manifold to help reduce NOx emissions. A properly functioning system has a few other minor benefits however, on the DISI MZR the EGR system primarily gets clogged,  and/or gums up your intake valves, reducing engine health and performance (for more info, check out our blogs on EGR Cleaning and Intake Valve Cleaning).

The CorkSport EGR Delete Kit removes the two primary components in the EGR system: the EGR valve and the EGR tube. This means no more carbon and soot going into your intake valves, and when coupled with a quality Oil Catch Can, much less frequent valve cleaning.

Each CS EGR delete kit comes with everything you need for a good looking, easy install. The EGR valve is replaced with a 3/8” thick, billet aluminum block off plate. The plates are precision machined to closely match the OEM EGR valve flange to keep your install clean. Proper length bolts are supplied with the CS EGR Delete Kit to ensure you won’t damage your OEM or CS High Pressure Fuel Line.

The EGR tube delete consists of two components: a laser cut 18 gauge T304 stainless steel block off plate and a T304 stainless plug. The plate can be used underneath the tube itself for a stealth install or for an even cleaner engine bay, go for the full tube delete and use the plug to block the hole in your OEM intake manifold.

While not a typical performance mod, the EGR delete is a great addition to aid in a racing build’s future mods. To start, the EGR valve block off plate is tapped for the included 1/8”-27 NPT barb fitting. This works great for the OEM turbo’s rubber coolant line, but should you upgrade to a non-water cooled turbo or a stainless coolant line, 1/8” NPT is a very common size that should be able to accommodate almost any type of fitting.

The CorkSport EGR Delete Kit also provides some much needed room around the turbo charger. With the bulky OEM EGR valve removed turbo swaps are easier, plus, certain turbo setups will literally not fit without an EGR delete. Finally, should you decide down the road to upgrade your Intake Manifold, an EGR delete is basically a must as nearly all aftermarket intake manifolds remove the EGR port from the IM.

The CorkSport EGR Delete Kit is a relatively easy way to gain some extra engine protection without breaking the bank. If you just cleaned your valves and want to avoid it doing it for a long time, a CS EGR Delete Kit is a must.
