    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快且壓力較低。擴散器的設計與功能是透過引導車輛底盤下方的氣流,幫助減少空氣阻力並產生下壓力。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。這會產生文丘里效應,意味著氣流在擴散器入口處加速,形成低壓區,進而產生下壓力。當空氣沿著擴散器全長流動時,高速氣流會逐漸減速,與車尾周圍的環境風速一致,從而降低整體空氣阻力。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,以幫助調節底盤下方的氣流。

    James E. ★★★★★

    The cut of those fins matches the bumper lines perfectly, and the brushed aluminum finish actually catches light nicely without looking tacky. I was worried about paint matching, but the bare metal look fits the WRX's aggressive stance just right.

    Jacob K. ★★★★★

    Bolted it on Saturday and the aluminum construction makes lining up the mounting points effortless, even on jack stands. The diffuser sits flush against the bumper and completely transforms the rear end aggression of my STI. Fitment was spot on for my 2019 with zero trimming needed.

    Riley K. ★★★★★

    The aluminum is seriously light—I can lift the whole thing with one hand, yet it feels rock solid once it's mounted. It transformed the rear end of my WRX and the aggressive look is exactly what I wanted for the track.
