Hi guys. Recently, I’ve been thinking about purchasing and installing an aftermarket air filter for my ’03 1.4 Leon. But, I have a few questions I’d like to run by some of you more knowledgeable folks before I do.
1. Would I stand to gain much (power-wise) by installing an aftermarket air filter on a smaller capacity engine?
2. If so, would an aftermarket air filter solely improve performance or would there be a noticeable audible difference too?
3. And lastly, are there any particular brands/models you’d recommend?
