Fresh air injected into the exhaust system on modified sportbikes can cause back pressure in the headpipes and muffler due to unburnt fuel from modified fuel mapping combined with additional oxygen spontaneously combusting in a high heat environment. Our blockoff plates will stop the annoying and possibly damaging back pressure from occurring while allowing you to remove a few pounds in associated valves and hoses fromyour bike. On late model EFI bikes with 02 sensors, ESPECIALLY when using Dynojet's Power Commander V with the Autotune feature, the air injection system MUST be blocked as it will introduce additional oxygen into the system which will skew your 02 sensor's values and make it impossible to get a correct tune.
Features:
- Driven Racing's emissions system block-o plates allow you to eliminate fresh air injection into your exhaust system with a simple to install, attractive package.
- Available for all late model sportbikes.
- Machined from 6061 Billet aluminum and then anodized black
- Kit comes complete with a cap for airbox.
- Note: Images shown are generic, each kit is designed according to spec for the application.
- Made in the USA

Drive block off plates Suzuki GSXR1000R 2021
The plates are nice quality but you cannot reuse the oem bots they are to long and will damage the threads in the valve cover when they bottom out before pressure is applied to the plate. I had shorter bolts on hand and had no issues. The kit should come with shorter bolts or just make the plates thicker by a couple of millimeters.

Wasn’t too hard to get a 5 star on this. But no problems, exactly what I needed with steel plates. STG is what makes everything better. Lowest prices and shipped within the next day. Always can be counted on for knowledge, and parts.

Nice block off plates just please request UPS for shipping instead of FedEx. If you've used FedEx lately you'll totally understand. Thanks Sportbike Track Gear (Brian) for another great product.

They block off, and they are plates
Pretty straightforward product. They are solid, with annodization that feels thick and sturdy, and they do the job.
