Features & Product Details

Over time and mileage, your factory intercooler coupler can become dry and crack over time due to engine vibration, and like all things, it can become deteriorated due to the elements. This could cause boost leak issues which will certainly limit your performance.

    Top mount intercooler to throttle body clupler 3 years ago
    4out of 5stars

    Good coupler, great fit. Great for replacements from the stock one. Only downside is comes with worm clamps not the Tbolt clamps in picture. Disappointing.

    I'm so happy I got this hose, all those comments that it's too short, that's not true with my car(2005 sti), the size / length is perfect! (USDM). Definitely recommending this piece.

        A:  We cannot confirm fitment with top mount intercoolers that we have not tested to fit. It is likely this may work but not guaranteed.
