I have some questions that could use some answering. I'm wondering which cold air intake product is better, SLP or whisper lid?

In terms of:
Ease of installation?
Sound?
Horse Power?
Price/Performance ratio?

Thanks

 

As far as I know all CAI are just about the same the price just varies.

 

Gains between the two will be very similar, but the lid will be alot cheaper and easier to install.

 

Ok great thanks. Think i'll get the whisper lid. I hope it comes with installation instructions.
