Aftermarket Air Filters (Simota, K&N)

[niky]

My car has 160+ hp at night, and about 80 hp at noontime. I'd say, yes... :hysterical:





Actually, hindi naman ganyan kasama... maybe I'm down to 130-140 during the day... heat soak in traffic is horrible! If you're worried about it, get a cold-air intake, or put heat shielding between the filter and the engine.

follow up question lang mga bos, do they (aftermarket air filters) increase the susceptability of engines getting hyrolocked in normal city driving conditions during the wet season (fording into deep floodwaters is definitely not considered normal )?

Sir, ano po yung hyrolocked ?

Well mas madali sya pasukin ng tubig kung sa mas madali, pero mahirap pa rin yun unless sobrang lalim ng baha.

Anyway, may tanong ako about aftermarket air filters. Particularly for EFI engines where the ECU injects gasoline based on how much air is being sucked into the engine, how does it help with fuel economy?

The usual analogy is parang tumatakbo ka na may panyo sa ilong and bibig versus wala, pero hindi naman sound yung analogy na yun dahil pag EFI, more air = more fuel. I see how it would give more power pero fuel efficiency?

Hydrolocking: It depends on the stock air intake design. If you're buying a cone filter and the stock intake inlet tube is headlight or bumper level, then water fording height is improved. If the stock intake inlet tube ends at a cold air assembly at hood level or higher, then water fording height is degraded.

If it's a drop-in replacement filter, no difference.

If it's a filter and snorkel, fording height improves. Can't make up for water soaking into the electronics, though. If it's a Cold Air Intake (usually bumper level), water fording height becomes ridiculously low, unless you include a bypass valve.

Fuel efficiency supposedly improves because less power is lost to pumping inefficiencies. But the gain is very marginal, if there actually is any... I've never actually noticed any myself.

hi guys newbie here...pero i've been browsing some of the chitchats here just like to ask if these aftermarket filters will not affect the shifting of auto tranny since sabi nila malakas ang hatak sa 1rst gear, i wonder lang if the automatic will shift agad rin sa manual kasi di agd maramdaman

thanks guys!!! nga pala dito rin ako nakakuha ng tips sa power steering problem..Cheers!!

[niky]

In my experience... no. The power effect (or non-effect... it's very small, anyway) of a cone filter will not affect shifting logic in any way.

Thanks Niky!!! I'm planning to buy K&N by the end of the month...although i'm kinda hesitant to choose between drop-in (less power, less noise) and cone type (more power, more noise)..

[niky]

If you're not a very aggressive driver, you don't really want a cone filter. A drop-in will be enough. It won't have a huge effect on power, but, subjectively, tip-in throttle response should be improved.

The biggest gains in terms of simple mods will come from exhaust tuning.

^reusable din ba ang k&n drop-in filters bro? and i understand it's more expensive than the cone type filters of the same brand

and is it true that in the long run switching to after market cone type filters would be comparatively less expensive than changing elements every now and then?
