Is your OEM splitter holding back your performance? If you're a proud owner of a 2006-2007 Subaru WRX or STI, you know how crucial it is to keep your top mount intercooler (TMIC) fed with cool, ambient air. The factory splitter can choke airflow, leaving your upgraded TMIC working harder than it should. Whether you've installed an STI scoop or are simply looking to maximize your current setup, the GrimmSpeed TMIC Splitter lineup offers the perfect solution.
With even mild modifications, your Subaru can generate significant heat. As your turbo compresses the intake air, temperatures can soar to over 400°F before reaching your TMIC. If you're still using the stock WRX splitter, you’re not harnessing the full potential of your intercooler. The GrimmSpeed splitters enhance airflow by a whopping 70%, ensuring your TMIC gets the cool air it needs to perform at its best. Larger TMICs can increase internal core volume by up to 200%, and you’ll want every bit of that additional airflow to keep your intake temps down.
One 2007 STI owner shared, “After installing the GrimmSpeed splitter, I noticed a significant drop in my TMIC outlet temps. Coupled with my STI scoop, it feels like my car is breathing better than ever!” Another 2006 WRX driver noted, “This splitter was a game changer. It fit perfectly and really helped with cooling during my track days.”
Don’t let your OEM splitter hold you back. Upgrade to the GrimmSpeed TMIC Splitter and experience the difference in performance and efficiency for your 2006-2007 Subaru WRX or STI.
