    Don't pass on this

    It may not be packaged from Stillen, but the look and quality is still the same. The only knock is that it doesn't come with 3M tape or screws. I could've installed myself, but took it to a body shop and they put it on in 20min, for $25. Even though it's not painted, the shine makes it look good enough not to. Just hit it with some spray wax occasionally and you'll be good.

    Good diffuser

    More affordable alternative to the Stillen diffuser! For those who are gonna buy, i recommend buying 3M Extreme double sided tape from Lowe's ($8), the tape they send you is trash. Scuff the diffuser where you're gonna apply the tape with sandpaper for good adhesion, and let the diffuser warm up in the sun for good pliability before installing! Very happy with the diffuser, made my maxima look next level. bravo Ikon

    Great Fit

    Easy install. Make sure you purchase 3M tape, 3M adhesive and self taping screws. Took me about 15 minutes, prep included. Good Luck

    Not bad for the price

    Obviously a knockoff the Stillen lip. Quality is ok, mine had a few chips on the reason/gel coat, fitment took some heat gun and force to get it to sit on the right location... Sanded it and filled itmin before painting it at home. Overall an OK product.
