There’s no denying the popularity of the Gen. III/IV LS engine family. And there’s no denying the performance potential of the platform either—which is exactly why the airflow and performance experts at Trick Flow Specialties are working tirelessly to offer more and more upgrade parts for the LS.
Case in point: a new pair of cylinder heads, a lineup of flow-matched fuel injectors, valve covers, and more.
The Summit Racing video team made a beeline to the Trick Flow display booth during the 2025 PRI Show in Indianapolis, Indiana to get an earful about this smorgasbord of LS upgrade parts. Check out the video at the bottom of this post for a bit more insight, and we’ll also give you some links to a few of the featured products below as well.
Long story short, if you’ve got an LS engine build in your future, then the Trick Flow website is worth bookmarking.
