Is a Injen sp short ram cold air intake worth it on a 2018 Mazda 3 hatchback touring 2.5 L!
Your "mechanic" is living in the 20th century and knows nothing about Mazdas. The Injen intake (or any other for that matter, they are all mostly the same) is only marginally better than the OEM air box which has been shown by tuners to be just a bit restrictive. You might see a couple hp when the intake air temps are low, but if you were to dyno the car the difference would most likely fall within the error tolerances of the equipment, so it would be hard to see any actual improvements..... If you were to do a 93 octane tune you would see about 10 hp from the SRI, but in stock form its mostly just bling.My mechanic told it will, because it not restricted and the one I’m getting is supposed to make the engine sound more aggressive!
Not likely to happen, as the OEM parts are already pretty free flowing....they need to be for the amount of exhaust scavenging the SA-G engine requires to operate at 13:1 compression.It may add 1-2 hp and sound louder ... you need to make your exhaust (headers/cats/down&exhaust) less restrictive in order to gain from a cold air intake which is really warm or hot from the engine bay unless you have air that is directly from outside the engine bay.
What was the power increase with just a tune?If you install it and perform an ECU tune directly after, I would get it. Without doing a tune, I would stick to the OEM CAI system (the car comes with a very well designed CAI system btw).
I've tested two different aftermarket SRI/CAI setups (K&N and AEM) and they both made almost no change in performance by themselves. With tuning they were able to add about 6 HP and 7 lb/s torque when testing on a v-dyno compared to the stock unit. I was mainly concerned with IAT and the AEM intake did a good job at keeping IAT closer to ambient. Not as good as the stock intake, but it was pretty close and it did a better job than the K&N Typhoon model. Cooler air is denser and has more oxygen to burn as fuel, which means better engine performance.
My Info was pulled off the OrangeVIrus website.Here is a thread with actual dyno test that shows results from a 93 octane tune on a 2.0 motor.
Just got the notification that my tune kit has shipped and will arrive tomorrow (9/16/16). I`ll be right around the corner from the Dyno shop today, so I`m going to stop in and see if I can schedule a series of runs to chronicle the tune improvements and get real world results.

Initial results show a 7 hp increase from the SRI when using an axle back exhaust.
Thats sounds about right for most. I have a couple different final tune options. The best hp out of those is 163 @ 5500. The best torque produced has a nearly flat curve from 145 @ 2600 to 140 @ 6200, peaks at 157 @ 3600.My Info was pulled off the OrangeVIrus website.
I am due to do a dyno and find what i now have at the wheels.
2years ago i did one 157whp ( OV Tuned with corksport CAI/ Catback exhaust/ & Lighter pulleys from here Mazda3 and Mazdaspeed3 Underdrive Power Pulley Parts. Mazdaspeed 3 and Mazda 3 Performance Parts. )
I need to do another once the summers are on to find out exactly where i am now with the current set up. Added since the last dyno was Cams from xerolimit, Ultra high flow cat (removed both OEm cats) , MSDS Headers, Lightweight flywheel (not that it will add HP but delivers the HP faster and lessen engine loud). What do think ? 200 whp ?That sounds
