Frequently Asked Questions

Are affordable performance parts worth the money?

Absolutely. Many affordable parts, especially those focused on maintenance, protection (like catch cans and thermal sleeves), and minor efficiency gains (like high-flow filters), offer significant benefits relative to their cost. They are excellent entry points for DIY enthusiasts.

What is the easiest performance upgrade for under $50?

One of the easiest and most effective affordable upgrades is installing a high-quality oil catch can. It’s a simple bolt-on process that immediately helps keep your engine’s intake system cleaner, leading to better long-term performance and efficiency.

Do dress-up kits offer any performance benefit?

While items like fender washers or battery tie-downs are primarily aesthetic, they often replace flimsy factory components with stronger, lightweight aluminum parts. In the case of the throttle cable bracket, the billet aluminum construction and adjustability can improve throttle response and reliability.
