Amazing

Throttle response and top end power is ridiculous compared to stock! Would recommend.

Great communication and fast shipping

Components for the intake are great compared to maybe the other only option available from another manufactured. Everything fits good maybe make the gasket fit better, other option would be to create your own intake system. Intake does what its intended to do provide more HP and reduce air intake temperatures with the heat shield provided, temperature gun states 125F on the intake side compared to 180F on the engine side this was only after a 15 min drive in Arizona with ambient temperature being 100F. Great intake

Fit nice and tight
100% recommend

Great product

it works really well it made the car run smooth again if I had two s4's I would tune that one too

Order shipped super quick as usual, showed up with no issues and is helping to keep IAT's in check. Would deffinetly recommend!

Was going for the black but the polished product looks good can’t wait for my mechanic to put it on. Awesome thank you . Switching to jackal tune next !!!

Im new to tuning so I needed a little help getting through the process. The customer service was second to none. I emailed several times with questions on the process and I received prompt responses to every question. Once I had it installed it tool a little driving to settle everything out and now the car drives amazing! I have a 2014 S8 and it was great before but this just made it better. Shifts are much smoother and the power seems endless. I assumed a tune would make the car jumpy but if anything it smoothed out the driving. Overall I am very happy with the product and customer service provided by Jackal and will be recommending them going forward.

Quality

Easy to use, the program for flashing is straight forward and easy to navigate. Plus if you do have a issue, email them, they have a quick response time. Matt is who I was emailing. "Great Service "! Mariano

The TCU tune alone was worth the price. The extra hundred horsepower was just icing on yhe cake! Wish I had done it sooner!

Loaded a stage 1 on my 2015 S4 and am very happy with the results. Keep up the good work Jackal.

Worth every penny!!!
