Boomba Racing

The best Boomba Racing part in this collection is the Boomba Battery Holder / Tie Down listed for the WRX 15-2019. If you own a 2015-2019 WRX and want to replace a worn factory battery hold-down, this is the part this collection is built around, so check your year and model against the listing before ordering.

A battery holder, or tie down, clamps the battery firmly in its tray so it cannot shift under braking, cornering, or vibration. A loose battery can chafe cables and stress its terminals, so the hold-down is worth checking whenever you clean up the bay or replace the battery. Because this collection holds a single part, the decision is mostly about fitment: the listing names the WRX for 2015-2019, and owners of other years or models should confirm compatibility rather than assuming the bracket transfers across generations.

Boomba Racing is the brand behind the part listed here, and this holder shows the side of its catalog this collection represents: engine-bay hardware that replaces a basic factory piece with a more finished, purpose-built one. A tie down is small, but it is visible every time the hood opens, which is why a dedicated holder works as a finishing touch. Treat the listing as the source of truth for what is included and how it mounts.

Three related engine-bay brands are worth knowing alongside it. Perrin is known for Subaru-focused performance and engine-bay parts, and its catalog suits WRX owners building a coordinated bay with matched hardware and covers. GrimmSpeed built its reputation on Subaru performance parts engineered in-house, from engine components to bay accessories, with a practical, function-first approach that pairs well with small hardware upgrades like this one. Mishimoto is best known for cooling, and its radiators, hoses, and catch cans are common companions to a bay refresh on a turbocharged Subaru.

Which WRX does this battery holder fit?

The listing names the WRX for 2015-2019. If your car falls outside those years, check your year and model against the product page and confirm the battery tray and hold-down style match before ordering.

Why replace a battery tie down at all?

The hold-down keeps the battery clamped in its tray so it cannot shift, chafe cables, or stress its terminals while driving. Replacing a corroded, bent, or missing factory piece restores that secure mounting and tidies the bay at the same time.

Is a battery holder a difficult install?

Hold-downs are among the simpler engine-bay jobs because they work with the battery tray rather than the engine itself. Work carefully around the terminals, follow the listing instructions for your car, and make sure the battery sits fully seated before tightening anything down.

Does this part add performance?

No — a battery holder is a mounting and engine-bay finishing part, not a power modification. Its job is secure battery retention and a cleaner bay, so pair it with the dressing and maintenance parts above if you are building out the whole compartment.
