Review on 🔫 AEM 21-8311DC Brute Force Intake System for Jeep Wrangler TJ 1997-2006 4.0 L6: Gun Metal Tube, Red Dry Filter, Charcoal by Juan Crane

Easy install, great results. This is perfect for my '04 Wrangler. I had a 4" crack in my intake manifold which was making an annoying whistling noise and could also bring dust and dirt into the intake manifold. After installation there wasn't much change in the sound but there was a really good change in acceleration. Plus it was nice to get the "old Wistler filter box" out of there. Make sure you have deep metric sockets and a 6" extension cord. I believe everything was 10mm except for the heat shield screw. 13mm if I'm correct When you start to take out the filter box, there are nuts on the bottom, so you may need a spare key.
