Come on, guys. You complain that their prices are too high, then ridicule them when they offer a sale? Badgering and insulting vendors will just scare away potential companies that might browse these forums, and then we'll have no one offering performance parts for your cars. It also breaks one of the most important rules of the forum:
Directly insulting other members is not tolerated.
In my opinion, $400 ~ $450 is a fair price for the first year high quality Air Intake product.
However, with save 30%, more people will be interested. PRICE vs DEMAND. Better than nothing or Never!
^ This, on the other hand, is a good example of a constructive post.
If you are that angry and upset about what D3 posted, you need to rethink your priorities, close your browser and get some fresh air. There's enough information out there (dynos, etc) to make an educated choice about an intake. If you don't think D3's intake is worth it, vote with your wallet and buy someone else's.
Let's keep this friendly, shall we?
