O'Reilly Auto Parts Unveils the Shamrocket

In 2015, the O'Reilly Shredder car was purchased and introduced as a show car, initially displayed on a circuit around the U.S.A. when O'Reilly Team Members took it to Grand Openings, events, and more. A few years later, it was brought to Springfield, Missouri, where it has been featured and used at select events, including NASCAR races, the O’Reilly Leadership Conference, and other notable occasions. At the 2023 O’Reilly Leadership Conference, the car’s new wrap was unveiled, and a contest was held to determine its new name—the Shamrocket. Today, we continue to use it as part of our activation display at various national motorsports events.

The 2025 Shamrocket Engine Swap

January 24-26, 2025, three influencers— all known for their ability to wrench and race — came together at the O'Reilly Auto Parts 2025 Leadership Conference in Houston to put their gearhead skills to the test by swapping out an engine on the infamous Shamrocket. What shenanigans would they get into? What roadblocks will they face? Watch and find out!
