A little pricey for a filter cover, but worth the peace of mind. Fits filter well. I haven't noticed any reduction in intake capability after install, so I am please with this product.

Just what I was looking for to put over my intake for the harsh winters to prevent dirt and excess water to reaching the filter

Perfect fit for the 2002 svt focus. I bought this with the intake system and installed it the day before it rained. Intake performs well with it on, i haven't taken it off yet because of fear of rain. Great buy so you can focus on the road and not water.

Although it does restrict a little bit of air for the intake when compared without the wrap, it is still worth putting on because you never know when you will ever come across in hitting a small puddle of water in accident or you are caught up in some rain while driving. Overall it is a great product because it gives you a sense of reassurance that small amounts of water will not be sucked up thru your intake and into your engine. I personally would rather be safe than sorry, even if it costs me an extremely small amount of air restriction for putting this wrap on.
