Custom Intake
Alright so I want to try and make a custom intake to help with air temp, since I know the one I have now sucks *ba-dum cha*.
The car came with the V2 Typhoon K&N intake. I would like to try and keep as many parts as I can to minimize the cost, going for low price and best performance. I have narrowed it down to the following 2 options.
1) Purchase the Air Cleaner Cover and modify it to fit onto the K&N filter I have right now if modifications need to be done.
2) Create a custom CAI using the K&N filter. Similar to either the DIY we have posted here or something like AEM.
I know if I did option 1 it would be better than it is now in terms of air temp, also it will make it a little quiter. My biggest issue is that the K&N filter might be too large to do either option and I'll have to buy a smaller filter if I want to do either. That's another topic I need to go over since I don't have the air cleaner cover and can't see the size of it, and taking the bumper off just to find out I can't do it would be a lot of wasted time.
If I did decided to do option 2, how much of a difference will it give me if I did option 1? Would it be worth the extra effort to make it a CAI? If yes, then when I need to clean the filter I have to take the bumper off just to clean it which is a lot more work than just going with option 1.
Wanting to get the mass' opinions/suggestions about this. Might do it this weekend if I have some time and the parts.

Intake
(can cause warranty hassle)
The OEM intake is really VERY good. The only 2 aftermarket intakes that can boast a power improvement are the Mazdaspeed and AEM. Which happen to be the exact same thing, just with different logos. That intake can give you a very slight bump in power. And I mean very slight. Within the 2% error margin of modern dynos. (2% of 180rwhp = 3.6hp). The only other viable intake for power reasons is the Racing Beat intake. There are a few other intakes that are net equal to the OEM intake, but not many. Every single other intake than this handful, from K&N to ebay kits, cold air and ram air, complicated and simple, every single one will cause you to lose power. This is because they do not have the proper R&D into how the air flows into our engine. They just fabricated a tube, made a port for the MAF, and jammed an air filter on the end. The air becomes heavily disrupted, the MAF can't read it right, and the ECU believes what the MAF is incorrectly telling it, causing the ECU to over and/or underfuel the engine all over the rev range. Even removing the OEM screens can cause power loss, since those screens are very well designed to straighten the air flow and smooth it down considerably. They aren't there to 'catch rocks'. Just to straighten the air flow.
The filter isn't even bad. There is FAR more breathable surface area on the OEM air filter than nearly every intake kit out there. The OEM filter is NOT a restriction on the air flow. The K&N drop-in panel was dyno'ed by Speedsource to show a consistent 1HP increase vs OEM. However, the K&N's filtering is substandard, and in Daytona races (Grand-Am ST class), they were losing engines to sand ingestion. (Reference: https://www.rx8club.com/tech-garage-...1/#post3849277) 1HP is not worth that risk, especially if you are paying for it. Stick with OEM. The only solid reasons to go after market are:
- the subjective reason of "I like the sound"
- or the improvement in how easy it is to get to any items under the OEM air box.
