Install takes about 30 min. I installed the scoops to introduce cool air to the engine compartment. I have dual cone intake open to the engine compartment and the scoops appear to do the job of introducing fresh cool air to the filters nicely. When installing, have some two sided tape handy. I used it to hold the scoops outer flange in place while re-installing the air duct.
LOWEST PRICES ON AFE COLD AIR INTAKES!!
I have a 2002 BMW 330i. I have long known of the quality of AFE and their cold air intakes. However this was my first time using Autoanything.com...I was blown away with the prices! They were not only lower than even Amazon, but much lower than any site or vendor I have ever found. Fast shipping, Simple install, Great product!
