Experience top-tier performance enhancement with the FAST LSXHR Intake Manifolds, meticulously designed for LS cathedral port cylinder heads. Crafted from durable composite material, these intake manifolds are engineered to optimize airflow and increase horsepower across a broad RPM range from 5,000 to 7,500. The design includes a complete intake section, featuring removable runners for versatile tuning and customization to suit different performance needs.

The intake manifold is equipped with multi-port fuel rails to accommodate your fuel injection system without requiring aftermarket modifications. While the throttle body and injectors are sold separately, the manifold supports a 103mm throttle body bore for substantial air entry. The finish is a sleek black plastic that not only looks great under the hood but also resists heat and wear for lasting durability.

Precision is key with sixteen machined supplemental bosses cast into the design, offering multiple mounting options for additional components or sensors you may need. The standard deck engine block height compatibility ensures a perfect fit for your LS1, LS2, or LS6 engines without any hassle.

This intake manifold kit comes ready to install, delivering the quality and innovation that FAST is known for. Whether you are building a hot rod, tuning a kit car, or upgrading your performance V8, the LSXHR series provides a reliable and high-performance solution. Trust Tuningsupply, formerly known as SminkPower.eu, for fast shipping across Europe and expert enthusiast support at every step of your build.

How much you like it, will depend on how much you paid.
Its just ok. I have a Klipsch the One, and I would say its slightly worse than that. So I guess it just depends on how much you paid. I paid, $58 with tax and shipping from Amazon, so I think its worth $60. BUT, I would have been said if I paid full price. Full disclosure, I've had a lot of Klipsch and other decent audio over the years so I'm a slight snob. That said, again for the money, it has a mic and battery (battery means its consumable trash) but makes for easy portable set up, its fine.

Solid choice for fuse holder
Size: 300A Fuse Holder
It’s awesome, solid connections for running 0 gauge wire. No issues after using for months! Might upgrade to using 0 gauge wire ferrules to use with this but for now everything is working well.
