Manifold Insulator Fitment Guide

I’m looking for advice on compatible upgrades for my car. I’d like to know what options would work best within my budget and goals. I already have a cold air intake, so I’m interested in any additional upgrades.
Given your $800–$1000 budget, the upgrades we’d recommend that represent the best value for money are shown in the links below. These upgrades are 100% compatible with your Pontiac G8 V6.
