AEM 21-703P Cold Air Intake System - Enhance Performance of Ford Fiesta 1.6L Review

According to my experience, the AEM 21 703P intake system did not provide any noticeable improvement in my car’s performance, even after installation by a professional mechanic. The promised increase in horsepower and torque was nowhere to be found. However, the product did have a sleek design. Unfortunately, its lack of functionality makes it a waste of money.

The installation took me 4 hours, but it was worth it. In particular, it climbs hills much faster. I've had it for about 4 weeks now and have fitted the filter with a weatherproof cover. Overall a good product and relatively easy installation instructions.

So I don't know if it's from Revain or AEM but the picture of the instructions shows what the pipe should look like and what they actually sent me. The diameter of the pipe is huge compared to all the other parts and the welded fasteners are arranged differently than shown in the picture. So overall a worthless purchase on my part and I won't be buying anything from them in the future. My mistake trying to buy auto parts from Revain.
