Anyone try K&N drop-in filter in their cam?

[Ken4]

Bought the 33-2145-1 panel filter for my '00 2.2L. My 0~100kph seems to be quicker by 0.1secs now. Anyone else experience good results?

many people say the k&N drop in filters are better than cone filters used as SRI, so you should see some gain.

I have a SRI and a K&N, i "felt" better response with the K&N over the stock.

I used have the K&N drop-in before I got my Injen intake. There was absolutely no gain. The gains you got are in your mind. Just the same with the SRI: no gains. You can't get gains from increasing the airflow to the engine through the intake unless you're force induced. Sure, you're getting more air, but the engine still continues to combust the O2 and Carbon (from fuel) at the same rate as stock, and continues to produce and expel CO and CO2 at an equal rate. Therefore, no gains. Only thing that you get out of an intake (not drop-in) as opposed to stock airbox, is slightly less throttle lag (due to faster airflow) and a louder sound from the engine bay since the stock resonator is gone.

Absolutely wrong. While I agree the gains from a drop in filter are minimal, the gain from changing an intake are there. It is due to reduced pressure drop as the volumetric flowrate of the engine increases. You likely wont see it down low where the engine volumetric flowrate is low, but in the upper rpms where the volume sucked in is larger the factory elements do start to become a restriction. The other benefit as you mentioned is increased throttle response, but really that is minimal on an NA anyway. Less pressure drop means a higher mass airflow rate, which in tern means more power. If the pressure drop is even 1psi in the topend, that is now 1psi more manifold pressure that your motor is seeing, for a decent sized increase in power (just for sake of figures here).

yes...it CAN make a difference....but you'll only "gain" power that you've lost before by having an inefficient filter


but a filter can't be any better than NO filter....therefore, the K&N filter is the best on available for air flow, but apparently not for actual filtering though


and about the best airflow- that is concrete, because having a clean k&n filter is the same as having no filter on the dyno- how do I know? because I dynoed it myself

[midnightmach]

I've seen a loss in power when people put new exhausts on, i figured its because there is less back pressure...could it be the same for intakes?

[2000LEV6]

i feel more power on mid Rpm on mine with Sri with K&N filter.

I bought mine about 6 months ago. When I first installed it, it seemed like I had just a tad better throttle response. But 6 months later, everything feels normal again.

Considering the V6 model uses the same air filter, I figured this is probably the least of the restrictions in the intake/exhaust.

Thinking about installing a TRD muffler one day.

yeah it does make a difference. I mean. the way i'm thinking of it is like a vacuum. If you have the same vacuum and stick that on a bigger hole.....the flowrate won't be so fast. you want it to be a decent size where flowrate is good and also the volume.

pretty much the same with exhaust. The engine pushes gas out....but it might have a harder time pushing it if the exhaust is too big. That's why you don't get a 4" exhaust on a 4 cyl car

that's my thinking anyway. oh yeah, the filters don't make almost any difference when it comes to how much air goes in. I had the K&N drop in. Doesn't do anything as far as performance. Might save me some money on filters but that's about it. Filtered compared to no filter dynos have almost no difference. i saw it in a magazine. Seafoam your car, you'll feel a difference there

I run K&N's on my Triumph & on My Corvette. Both cars have performance exhausts, and head modifications.

The filters don't do crap for performance. I bought them for the Triumph because they are reusable and its hard to find anything for that car. The Vette came with one.

I wash them about every 3 months or 1000 miles, whichever comes first. They get dirty very quickly. Get the better muffler, and just change your air filter with a regular paper one on a regular basis.

i had a drop in filter before i put on my SRI with a K&N cone. they were about the same. i Noticed a VERY VERY SMALL gain up at about 5-5.5k

the drop in didnt fit very well either. i had lots of trouble getting the lid to close.
