Customer Reviews
Good Intercooler Upgrade
I ordered the FDS Intercooler for my Audi S3. The website was easy enough to navigate. Shipping took about 5 days to reach Denver, which was reasonable. Installation instructions were clear, and the part fit perfectly. I noticed a pretty immediate difference in sustained power during longer drives, especially in warmer weather. Their support actually answered a fitment question I had before buying, which was helpful. Overall, a solid product and experience.
Fast shipping, great part
Bought the Carbon Fiber Intake. Arrived quickly. Install was straightforward. Looks and sounds great under the hood. Very happy with it.
Amazing Tune!
Got the Stage 1 Tune for my Golf R and it's incredible! My car feels like a whole new beast. The POWERlink tool was super easy to use, literally just plugged it in and followed the steps. The power increase is seriously noticeable, makes driving so much more fun! I'm definitely coming back for a Stage 2 when I get a downpipe. Highly recommend this to anyone looking for a power boost!

Can I use like a free shipping code and also get the automatic Black Friday discount on a tune? Or is it one discount per order kinda thing?
Anyone know if IE does military discounts? I saw some talk about it but couldn't find a direct link on the site.
Does IE actually make their own parts or are they just rebranding stuff? Heard conflicting things.
Trying to decide between the IE cold air intake and the 034Motorsport one for my S3. Any thoughts on which one performs better or fits nicer?
Hey guys, thinking about grabbing that IE Stage 2 tune for my GTI. How long does it usually take to get the POWERlink and everything shipped out? I'm in NYC.
