RBC and RRC manifold swaps are a popular solution for engines equipped with less desirable intake manifolds like the 2012 2015 9th Gen Honda Civic Si, 2013 2015 Acura ILX, 2009 2014 Acura TSX or

2012-2015 Honda Civic Si 9th Gen Civic RBC Intake Manifold to 70mm J37 Throttle Body Adapter by PRL Motorsports

It's no secret that Honda's RRC and RBC intake manifolds are some of the best flowing intake manifolds available from Honda for the K-Series engine. RBC and RRC manifold swaps are a popular solution for engines equipped with less desirable intake manifolds like the 2012 - 2015 9th Gen Honda Civic Si, 2013 - 2015 Acura ILX, 2009 - 2014 Acura TSX or 2008 - 2012 Honda Accord. Often times these manifold swaps require a throttle body adapter. We offer a billet throttle body adapter machined from 6061 aluminum to seamlessly adapt a specific DBW or drive-by-wire throttle body to the intake manifold. A 70mm ZDX / MDX throttle body upgrade is a great way to increase airflow for these newer DBW K-Series cars. It offers OEM reliability and drivability at an affordable price.

This throttle body adapter utilizes an O-ring to seal against the intake manifold and OEM Honda gasket to seal against the throttle body. A 1/8" NPT port and 90 degree fitting retains the factory EVAP Purge, but can also be deleted or plugged for a cleaner install. EVAP can be disabled with an engine tuner like Hondata FlashPro or KTuner.

Cool, modern look
Color: Army Green, Size: Large
I bought this for my husband and looks great! The material is a little clingy, so I would get a one size up for a better fit. He has received numerous compliments. It fit him well and I washed it but played it flat to dry with no shrinkage problems. I highly recommend it. We ordered another one in a different color.

Too big
Color: Pink, Size: Medium

low-maintenance shirt that fits perfectly
Color: Black, Size: 3X-Large
This COOFANDY Casual Button Down is a fantastic addition to a summer wardrobe, offering both great fit and high quality. The material is impressively wrinkle-free, which keeps it looking sharp and crisp even after a full day of wear. It is specifically designed to be worn untucked, and the length is just right—offering a modern, relaxed silhouette that doesn't look sloppy. The fabric feels durable yet breathable, making it comfortable for both casual outings and slightly dressier occasions. If you’re looking for a low-maintenance shirt that fits perfectly right out of the wash, this is an excellent choice.
