I felt like I was driving a different jeep after the install n I love how it makes the motor sound. I recommend an exhaust upgrade with this purchase as well. ### ⭐⭐ 2.0 out of 5 stars Two Stars *by J***S on Reviewed in the United States on March 20, 2015* I have big gains but i did not receive the throttle body. It wasn't in the box. ### ⭐⭐⭐⭐ 4.0 out of 5 stars First Buyer *by M***M on Reviewed in the United States on December 9, 2014* I was skeptical at first because there were no reviews on this package but i purchased anyway, i got the package in about a week. Cant open tell christmas so I'm dying. Bought for my 08 Jeep Jk, my buddies said i should use the 87 octane settings, im juSt looking for a little more power along with better air flow and the superchip should make everything run smoothly. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/10560529-superchips-387526-trail-jammer-ext-performance-kit-for-jk-wrangler](https://www.desertcart.be/products/10560529-superchips-387526-trail-jammer-ext-performance-kit-for-jk-wrangler) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-08*
