A thread which finally has good thinking people discussing the facts,am really proud of you all
This reminds me of a thread where i had suggested to a newbie member that it wont give you much power,but some want to believe adding such an airfilter will perform miracles(that would be true if your airfilter was clogged also) ,just check out until post #9 where i decided i wont comment anymore http://www.theautomotiveindia.com/fo...otton-k-n.html
(dont want to offend anyone who wants to believe so,cos you are entitled to yours) but to realize the facts just go ahead & look at some turbo swifts they just have like 2 sec improvement to 100,so here someone adds a stock replacement filter & whoss nos like power really??
Unless your stock airfilter was really messed up bad you wont notice anything diff(maybe intake sound).
I agree with "jarpickle" that most of this is down to mental HP(imagination),like a exhaust end can on a car can make you feel like its from The Fast & the Furious.
And i have driven some cars which had these filters(even i wanted them at one time,atleast for the sound),a Accord 2.4 with replacement filter & Mugen End can,but most observed was my friends Zen which had a conical with custom intake pipes,but it was not exactly a cold air intake cos worry of water being sucked in was there ,car sounded amazing for first 6000 kms after which it sounded clogged,so after having it washed at 8000 odd km it sounded rev happy but never sounded the same & we had suspected after some running the washing solution left behind in the the airfilter was coating the sensors,before we knew it the car was feeling clogged after a few thousand km,so my friend gave up in pursuing performance from it,he rarely uses it,but he has gone diesel,since most of them are very fast anyways,
Another friend had changed to k&n(twin)on his Rd350 claimed a power increase,but it had a good free flow setup so i guess the filter did well in sync.
As for the Superbikes they claim to be helping after gaining speed,i guess this is due to lesser resistance as air passes through the Ram air intake,but as i have realized,you are totally messing up your engine even further,most of the Superbikes are screwed by the time they hit 15000 km anyways.
There is nothing wrong having a K&N or other brand filter in your car,but one must be realistic of the pros & cons.Remember mild improvement in throttle response does not mean increase in power.
