So you’ve got an LS stuffed under the hood of your classic car or truck. You’ve done all the big stuff so it’s down to a handful of seemingly small details, building an LS swap air intake system being one. Seems like an easy task, right?

Here’s the thing, every LS swap is a little different. You’ll be hard-pressed to find an LS swap air intake kit that properly fits your specific application. That is where Classic Performance Products (CPP) comes in.
We’ve done our fair share of LS swaps and we always choose to put together our own intake tubes and filter, optimizing each engine bay individually. We decided to take a moment and show you how you can do the same.

Below you’ll find a step-by step example of how we put together an LS swap air intake system on our C10 Chevy. We did it using both pre-formed ABS plastic and polished aluminum so you can see a couple options. You’ll also notice the table showing all the individual parts we used and their part numbers. Just give CPP a call, tell ‘em what you need, and you’ll be on your way to building your own custom intake system.

(Note: most intake systems will benefit from a brace to support the tubing. Keep reading or watch the video to see the bracket we made for the polished aluminum system.)
