    I have been installing K&N on every single vehicle my family owns. From drop in filters to full CAI! This kit came with everything and very clear instructions, with pictures!! I have noticed some more get up and go, but that’s just with my in the seat dyno. MPGs are up from 0.5 to 1mpg average city/highway. Will continue to use K&N. Item was an open box. Came with everything listed and didn’t disappoint. Thanks for all the effort in posting the open box photos and descriptions.

    Love this kit. Easy install, straight forward. Sounds really good, can definitely tell a difference. You can also hear the turbos with the windows up now, which I appreciate. Good BOV sounds as well! Gained maybe 2-3mpg on average.

    If you’re looking for an amazing sounding intake this one is for you. At low boost you can totally hear the turbos spooling like a mini diesel. It did throw a code but after telling the tuner they made it go away

    Product was easy to install and quality of components were very good. Fit and finish was spot on. Gained a few .1 mpg so far and now can hear the turbo’s spooling up.

    Pretty much worked out all the jumpy shifts in my transmission. Overall, truck breaths 100 times better. Turbo sounds quadruple in loudness.

    I can confirm the 2-3 MPG improvement. Don’t waste your time with the series 63. This is well worth the extra $$.

    Gave a little bit more power and a nice boost in sound.

    I love the look of the intake. The turbo sound is amazing with an awesome blow off sound. I give it three reviews due to the poor quality control. The ends of both pipes were dented in and deformed. This made it very hard to fit it into the intake and clamp it down. The endings were more oval then circle. The clamp kept sliding off due to the deformity of the intake, and probably added at least 45 minutes to my install. I finally got it and it seems sealed. I love this intake, but the install was way harder than it needed to be due to the defects. I probably should have returned it, but it ended up fitting so I’ll live with it.

    Sounds good expect the check engine light keeps popping on.

    Unfortunately, my K&N 77 series did not work out for my 2019 F150 . I kept getting a check engine light. Took it took to have Code read , said vacuum hose disconnected. I made sure everything was plugged in correctly and tight, but no luck . Had to install my OEM back in . I will need a refund since there’s no use for it.
