There are heaps of debates over the filters (pod or panel) and how good they actually

are for your car.

chicane is right - partition it off otherwise you will be sucking in ALOT of hot air coming off

the engine.

The debate is; that some filters have very good air flow but poor filtration, thus getting

dust and particles into your motor, where as other filters have poor air flow but are doing

what they are meant to be doing and that is to FILTER particles and crap. It will depend

on where you live, ie. dusty area, or nice clean area.

Best you can do is keep it oiled, and build a nice solid partition to keep heat and unwanted

crap out. You can buy one for about 150ish or build it yourself, I just recently built one myself and you can stick on hand in the engine bay area, and other in the pod partition area and really notice a difference in temperature after a spirited drive.

K&N, Blitz, Apexi, Unifilters - they wont vary by very much, the most you'll get is an additional or negative few kw

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
