Review on 🚀 Spectre Performance Air Intake Kit SPE-9963: Boost Horsepower & Torque for 2007-2011 TOYOTA Sequoia & Tundra by Carl Estell

The quality of the set is excellent. Although I think they need to update their instructions, although they were easy to follow (although this wasn't my first air intake installation), the instructions mentioned 4 bolts to attach the speed stack to the heat shield. While the heat shield had holes for 4 screws, the speedstack had no holes, and there were no screws for this step either. It installed perfectly without those 4 screws, which leads me to believe they updated their design but not their instructions. One thing that did happen, however, was that the filter barely slipped off the other end of the speed stack. Realizing the bike stack was pretty slippery, we wrapped it in electrical tape and attached the filter to it. Problem solved. He just needed a little more traction. We're already seeing an increase in fuel economy with our Tundra, as well as a response to the accelerator pedal. And the intake noise is great. I would like it to be louder, but that's all a matter of personal opinion.
