**********THE OFFICIAL INTAKE/ TURBO INLET PIPE THREAD**********

NOTE: This is an informative discussion and a resource for gathering information on which route to go (Short Ram Intake, Cold Air Intake). All-in-all it is up to you on which you decide to go with.

Abbreviations used on this sticky:

Gen1 MS3---> Mazdaspeed 3: 2006-2009
Gen2 MS3---> Mazdaspeed 3: 2010+

Difference between SRI and CAI: According to research and discussions there are inherent pros and cons of both intake systems, but the main difference between a short ram intake and a cold air intake is where the intake gets its air from. A short ram intake sits and the engine bay where the air temps are warmer due to the heat the engine produces while a cold air intake sits away from the engine bay, usually in the front fender where it can suck in cooler air from the outside. Sucking in cool air is important because cool air is denser than warm air, which means cool air molecules are closer together, so more air can fit into a given amount of space. An engine creates power by mixing and compressing air and fuel. The more air you can fit into a cylinder at one time, the bigger explosion you can create which in turn creates more horsepower.

NOTE: I've decided to list the filter covers first because I noticed that people have expressed concerns about water penetrating their engines with the cold air intake systems. First, it is HIGHLY unlikely that this will ever be a problem. Rain and water droplets are no problem. The only case that could be a potential threat is if you drove into an extremely deep puddle, submerging the intake head. The car would have to be in the water so that the intake was submerged, and then it would start sucking up water, making your engine hydro-lock.

Intake Kits: SRI, TIP, CAI

CAI

Cold air is denser than hot air, and will ultimately have more power producing potential. Cold air induction (CAI) provides colder air than SRI / TIPs and can provide 12% more power and torque, but experiences pressure drops associated with the longer tubes used and are prone to easily hydro-locking in deep puddles (MSF wiki). Therefore, SRI / TIPs with air-box are the preferred option. Use a filter cover (CP-E, Outerwears. AMSoil) and / or splash shield (CP-E, Sure) if you are concerned about rain and water droplets, but they will not prevent hydro-lock if your intake is submerged.

SRI / TIP

Points to consider when improving the intake airflow are the future needs, such as BT for the K04 will most likely fail at some point. Although some members progress through different BTs, perhaps choosing a three inch intake initially will prevent having to replace it again later. The only problem with this course of action is that a MAF calibration must be done, which requires an ECU re-flash. See the “Larger than stock MAF housing” calculation below installation time in this section.

TIPs can flow 14% more, but are usually limited by the SRI. The main advantages to TIPs are the reduction of backwash turbulences away from the MAF housing from the blow-by valve and PCV.

However, SRI / TIPs allow the turbo to spike more easily. (Cobb) Note that with no other changes, tilting the MAF more than the OEM 15 degrees causes over fuelling with the ECU removing fuel through large negative LTFT and you exceed your previous g/s readings during WOT. MAF recalibration is strongly recommended.

Larger than stock MAF housing offers larger cross section for more airflow, but has less cooling to the MAF resistors due to the decreased air velocity. In order to develop a scalar for a larger than stock intake diameter, you must take the (New MAF Cross-Sectional Area) and divide (/) it by the (Stock MAF Cross Sectional Area), which is technically pi * radius squared (Djuosnteisn), but you can actually just take the new diameter squared / old diameter squared (ms3blackmica). Say you decide to upgrade to a 3" intake (76.2mm). The stock MAF housing is 66.5mm diameter (2.61811").

(76.2^2) / (66.5^2) = 1.313

Take 1.313 and multiply it by the entire MAF curve. Now you are ready to start your MAF Calibration. This is only an example for a 3" intake. (ms3blackmica)
