Your Subaru’s engine delivers plenty of performance, but when you pop the hood, the factory styling doesn’t exactly impress. From the dull yellow caps that fade over time to the basic black plastic alternator cover, the OEM setup leaves a lot to be desired when it comes to looks. Whether you’re getting ready for a car show, putting the final touches on your build, or just want to add a little custom flair under the hood, we’ll walk you through some of the best ways to dress up your Subaru engine with options from IAG Performance.
The IAG VA Fender Shrouds are a quick way to clean up the engine bay edges on 2006–2014 Subaru WRX and 2004–2021 Subaru STI models.
STEP UP YOUR SHROUDS
One of the first things you might notice when looking under the hood of your Subaru are the unsightly factory fender shrouds near the strut towers. Made from flimsy poly-foam and flocked in material that fades and traps dirt, they don’t hold up well over time—and they don’t do your engine bay any favors in the looks department. The IAG VA Fender Shrouds are a solid replacement, designed to clean up those gaps with durable aluminum panels that follow the contours of the VA chassis. The precision fit adds a clean, refined look, while the hex-cut design allows airflow around heat-sensitive components. Each shroud is powder-coated black and paired with a second color plate that shows through the cutouts for a custom pop of color. With multiple color options and a quick, no-drill installation, you can sharpen up your Subaru’s engine bay in just 15 minutes.
DITCH THE FACTORY PLASTIC
Right in the middle of your engine bay sits the alternator cover—and unfortunately, the factory version is just a basic plastic panel that does nothing for the overall look. If you're already adding custom touches elsewhere, this part starts to stand out for all the wrong reasons. The IAG Alternator Cover is another easy solution that replaces the OEM piece with a more durable, more attractive alternative featuring IAG’s signature hex pattern and the same high-quality aluminum construction as the IAG Fender Shrouds. It also shares the same color options—red, neon yellow, black, white, blue, or pink—making it easy to achieve a cohesive look throughout your engine bay.
Tidy up the center of your engine bay with the IAG Alternator Cover—an easy, direct-fit upgrade for 2006–2014 Subaru WRX and 2004–2021 Subaru STI models.
The IAG Revolve Cap Kit replaces faded factory caps with anodized billet aluminum upgrades for Subaru WRX, STI, BRZ, FXT, and LGT models.
DONE PRETENDING THOSE CAPS LOOK FINE?
It's hard to look past the factory caps once you've started cleaning up your engine bay. Between the faded yellow color and cheap plastic construction, they stick out like a sore thumb—and after years of heat cycles and grime, they usually don’t look (or feel) any better. The IAG Revolve Cap Kit gives you an easy way to get rid of those eyesores once and for all. Available as a complete kit, it replaces your oil, brake, clutch, coolant, washer, and power steering caps with anodized billet aluminum versions that fit Subaru platforms like the WRX, STI, BRZ, FXT, and LGT with factory-level accuracy.
THESE CAPS AREN'T JUST FOR SHOW
The caps in the IAG Revolve Cap Kit don’t just clean up your engine bay—they’re built to last. Each one is precision-machined from 6061 billet aluminum for better heat resistance and durability than factory plastic. The anodized finish holds up over time and adds a premium look. At the center of each cap is a removable insert, available in silver, red, blue, black, gold, or purple. Each insert is laser-etched with the correct fluid symbol—oil, brake, clutch, coolant, washer, and power steering, but can be flipped to show the solid color. The inserts are easy to swap in seconds, thanks to the accessible design inside each cap—just use a small tool to pop the insert out and choose your preferred side.
Flip to fit your style. The IAG Revolve Cap Kit features reversible inserts so you can show either a sleek anodized finish or the correct fluid symbol—perfect for your WRX, STI, BRZ, or FXT.
The IAG Billet Dipstick replaces your OEM Subaru plastic handle with CNC-machined aluminum that looks better and lasts longer. Fits EJ 2.5L (2004–21 STI, 06–09 Legacy), FA24 (2022+ WRX, 2019+ Ascent, 2024+ Outback/Legacy), 2022+ BRZ, 2015–21 WRX & 14–18 Forester 2.0L, plus 2002–05 WRX and 93–06 Impreza.
THAT YELLOW HANDLE HAS TO GO
The factory dipstick does its job, but the plastic yellow handle is a real vibe-killer. The IAG Billet Dipstick replaces it with a CNC-machined 6061 aluminum handle that looks right at home in a clean engine bay. Finished in your choice of anodized silver, red, blue, black, gold, or purple, it’s a simple upgrade that adds style without compromising function. The stainless steel stick is flexible and durable, with laser-etched markings for accurate oil level checks. Best of all, the dipstick’s anodized colors perfectly match the IAG Engine Bay Dress-Up Cap Kit for a more cohesive look under the hood.
DETAILS MATTER
IAG Radiator Stays are a simple but stylish way to clean up the engine bay on your 2002–2007 WRX, STI, Impreza, or Outback. Designed to replace the factory brackets on models running a stock radiator, these precision-machined 6061 aluminum stays feature a corrosion-resistant anodized finish in the same great colors as the IAG Revolve Engine Bay Dress-Up Caps and Dipsticks—silver, red, blue, black, gold, or purple. Finished with a laser-etched IAG logo, they offer a stronger, more refined alternative to stock hardware and tie in perfectly with the rest of your under-hood upgrades.
Replace stock radiator brackets with anodized IAG Radiator Stays—stronger, better looking, and designed to match the rest of your IAG engine bay dress-up parts. Fits 2002–07, 2008–14, and 2015–21 Subaru WRX and STI platforms and more.
Swap out the stock battery bracket for the IAG Battery Tie Down—built from stainless steel with bold color inlays to fit all Subaru models, 2013–2016 Scion FR-S, 2017–2020 Toyota 86, 2022–2024 Toyota GR86, and 2005–2006 Saab 9-2X platforms.
FINISH STRONG
Let’s be honest—the factory battery bracket isn’t exactly a showstopper. The IAG Subaru Battery Tie Down steps in with a rugged 304 stainless steel build and a sleek black powder-coated finish. It’s the color accents that really stand out—bright aluminum plates peek through hex cutouts in your choice of red, neon yellow, black, white, blue, or pink. It installs easily on the factory battery base using the original hardware—no cutting, no hassle. Want the full effect? Pair it with IAG’s matching Fender Shrouds and Alternator Cover to bring the whole engine bay together.
