Hey everyone. I'm looking for some opinions. I have been looking at the Cervinis ram air kit for a while now. I'm trying to decide if it is worth the trouble/risk of installation vs just using a typical CAI with a downspout. I know your not going to get a ton of gains from either one, but I'd like to know if the ram air kit has better air flow than your typical CAI. If you have one, do you feel like it was worth it? If you had a typical aftermarket CAI, would you still replace it with the ram air kit?
I currently have a Corsa closed box intake similar to the one in the link below. I like it, but it can be a real PITA to replace the air filters and the replacement filters are around $95 a pop. Just curious to see what others experienced or your opinions on the subject.

This is the link to the ram air kit in case you haven't seen it:
Your "typical" aluminum down tube hung off the throttle body with a cone filter on it, all of which rest inside the engine bay is not an actual "ram air" system, nor is it a "cold air" system, despite the "CAI" tag line some manfs apply to them.
Its simply pulling
in hot underhood air, is subject to heat transfer from the aluminum tube to the incoming air charge and serves zero perf increase. Think about it. Your underhood temp is hot, compared to outside. It also is mostly static in regards to flow - again, compared to the outside of a car in motion - why would anyone want to suck hot underhood air in and think its going to help perf.
Its almost opposite of even basic logic.
Hemis love cold air, lots & lots of it, as do most engines. so in many cases, a system like that is actually hurting perf. This leads to buyers claiming that CAI's are not worth any gains. They simply have an poorly designed system, built by peiople who do not care to understand how it all works.
Cool air, drawn or better still - forced in - from outside the car - will help perf. Its not huge gains, but 8-10hp is not uncommon from a good system. Like many things, it works in conjunction with other systems. So its not always a "gain" in HP, but rather a maximization of all potential HP that engine is capable of, in its current state of tune, controls, etc.
To answer your question, the Cervinis looks like a very viable option. Air coems in from the high pressure zone of the hood where air is both cool and under pressure and flows it directly into the air box via the ducting. Perfect and is a true CAI.
IMHO, thats the best system for pre 15 challengers. The only flaw to that system is the small size of the hood scoops themselves.
