"It was great service and attention to my questions. Perfect"

"Great and fast customer service"

"IE definitely delivered on their promise. The stage 1 tune is a night and day difference. It’s something you definitely have experience for your self."

"I purchased a tune from them after much deliberation because of the features they are adding and flexibility that no one else is offering. When I received it there was a slight issue with the tuning credits and it was a Saturday so I thought I would have to wait to install it. Despite being closed on saturdays they emailed me back telling me the issue has been fixed and I couldn’t be more impressed. I would 100% recommended them to a friend. It’s been a great purchase experience."

"Much more torque down low and now pulls hard to redline. Love it!"

"Great customer service and excellent updates on the order and delivery compare to USP Motorsports"

"Great products, service and fast shipping. That sums it up."

"I was very excited about my order by itself but when it came I realized they included their “swag pack” which included an IE coozie and a few cool decals that I will proudly display. Thanks again for the awesome product!"

"high quality parts and dirrect shipping"

"I received my cold air intake and it did not fit my 2008 Audi s5 4.2L B8 but when I ordered it and gave the vehicle make model and year it was a fit hmmmmm?

Waste of money. I called and the gentleman who answered was no help, and knew nothing about vehicles. He told me I’d have to figure out how to make it work? He offered no alternative or return scenario or replacement and was halfway rude about it. So it turns out the high performance part I ordered is for a B8.5 v6 wouldn’t fit my throttle body the online directions are terrible.

I ordered a intake tube from 034 motor sports I had to leave my wife’s S5 at home and order it from a company that knows the difference in a 2008 s5 V8 and a 2013 s5 V6 what a shame thanks for the stickers though I’ll make sure I hand them to all my friends with high end sports cars and tell them to avoid you like cancer!"

"No stock when the website says there is... One month waiting todo know there is no stock and finally cancel the order"

"They had a slight miscommunication regarding a item that was out of stock, but they were able to email me and get this issues resolved in a timely manner. I will definitely continue to purchase for them (: "

"High quality materials and performance was beyond my expectations. Thanks"

"Excellent product! Excellent customer service. My car was transformed into the luxury performance sleeper I wanted it to be. Thanks IE! Can’t wait for stage 2!"
