Magna-Fi (known originally The Szuters) is the rock project of American musician Mike Szuter. From 1996 to 2010, it was a rock band consisting of Szuter as guitarist and lead vocalist, bass guitarist Rob Kley, drummer Charlie Smaldino, additional guitarist Christian Brady, and CJ Szuter. They were perhaps best known for performing on the 2005 Shadow the Hedgehog (2005) video game soundtrack, as well as their single "Where Did We Go Wrong", which was used for the 2005 NASCAR Nextel Cup Series.

In 2020, Szuter revived the project under The Szuters name, releasing the album Sugar that same year, followed by The Devil's in the Details in 2021.

Lead vocalist Mike Szuter started the earliest version of the band in Cleveland with his brother and lead guitarist, C.J. (both guitarists and vocalists, had played together since they were 10 and 11 years old), gathering a local following across Ohio performing as Outta The Blue at first, and later as the Szuters. The band later moved west to Las Vegas and met Charlie Smaldino and Rob Kley, who would both join the band as their drummer and bassist respectively. Around this time, they changed the band's name to Magna-Fi. The band would go on get signed to Aezra Records, a record label distributed by EMI, in 2003. Magna-Fi's debut album on the label, Burn Out The Stars, would be produced by Paul Lani (Megadeth, Failure, Mötley Crüe).

In 2004, Magna-Fi appeared on the weekly concert series in Buffalo, New York, Thursday at the Square along with Fuel and Seven Day Faith. The band at that time for 2 months was direct support for Fuel. In the same year, they appeared at the annual festival tour, Ozzfest. Afterwards the band headlined their own tour and became direct support for Sevendust for months after. They also made a returning home for veterans show in North Carolina, after a sudden Sevendust cancellation.

At the end of a tour in 2006, they were in talks with Aezra about recording a new album, but these discussions ultimately ended with the quartet and the label parting ways, and the band decided to record their next release on their own. This also marked the exit of C.J. Szuter and the entrance of guitarist and vocalist Chris Brady, another Las Vegas native and long time friend of the band. The new album, VerseChorusKillMe, was recorded and mixed by the band itself.

In 2010, drummer Charlie Smaldino, after not playing with the other members for over a year, getting turned down by various record labels, and losing interest, decided to have a final show at Counts Vamp’d in Las Vegas. The group officially disbanded afterwards.

In 2019, Mike Szuter held a small venue at a restaurant in Ogden, Utah for free.

In 2020, Mike Szuter revived the "Szuters" moniker for a solo project and released an album titled Sugar.
