    後擴散器是一種汽車空氣動力學改裝件,通常安裝在車輛底盤後方、後保險桿下方。車輛行駛時,底盤下方的氣流通常速度較高且壓力較低。擴散器的設計與功能在於透過引導車輛底盤下方的氣流,幫助減少阻力並產生下壓力。擴散器可沿其全長增加空氣體積,從而形成一個需要由空氣填充的空間,進而產生文丘里效應,使氣流在擴散器入口處加速,形成低壓區,從而產生下壓力。當空氣沿擴散器全長流動時,高速氣流會逐漸減速至與車尾環境風速一致,從而降低整體阻力。擴散器上附加的垂直「鰭片」有助於確保所有進入擴散器的空氣均來自底盤下方,而非車身上方表面,從而優化擴散器的效率。擴散器可進一步搭配前分流器進行調校,以協助調節底盤下方的氣流。

    Penelope F. ★★★★★

    Took it out of the box and was surprised by how light it is—that aerospace aluminum really shows. Bolted up cleanly to my 2019 WRX with no fighting or gaps, and the V6 look is way more aggressive from behind now.

    Alexander L. ★★★★★

    The weave of the aluminum has a real quality feel to it, and the fitment on my 2018 WRX was spot on. Bolted up with zero drama and it gives the rear end that aggressive STI look I was after.

    Elizabeth R. ★★★★★

    The aluminum is seriously light—I forgot it was even in the box when I lifted it out. Bolted right up to my 2018 WRX with no fuss, and the V6 shape gives the rear end a much more aggressive stance.
