Hey I'm kind of hesitant from doing many engine mod's only because I'd like for my car to last a while. Does anyone know some of the negative side effects from doing a CAI or with a K&N filter? thanks

 

As far as know, there are none except for maybe a slight whistling or sucking sound from the intake at certain rpm's. It's really not very noticeable unless you listen for it.

 

i heard from an old forum i was on that the K&N didnt filter very good and that small bits of dirt or something will build up in the MAF or something, i cant remember so far back. i could be wrong. (doesnt MAF mean mass air flow? remember i cant think so far back)

 

But i think with the CAI you have to be careful of not sucking in water, i.e. when it rains and there is puddles and stuff. You dont want water in your engine, i know that much.
Y2KEVSE, can you verify this?

The shop-vac technique is interesting. Which is better performace-wise? The Hi-flow or the OSCAI? Or are they the same?

 

ToYlet902: lots of people here and for many other makes of automobiles have used K&N filters without any problems. If you keep the filter clean and well-maintained, you should hopefully have no problems. I think what you mentioned was happening because people were installing the filter when it had too much oil on it after re-oiling it. The excess oil could build up in the TB or on the MAF (mass air flow) sensor and damage it. If you let the excess oil drip off the filter after a re-oiling, things should be ok.

radpp16: with a CAI you have to be careful not to drive in flooded areas or areas with standing water. But, driving in rain should be OK. I don't think anyone here has ever had a problem with water ingestion because of a CAI. With the OSCAI you can adjust the tubing to make sure it is out of the way of water if you plan on driving in such situations. I have driven with the OSCAI in heavy rain before and have not had any problems. No water in the air box or water marks on the filter ever.

VeggieH8R: The underhood style intakes such as the Stillen Hi-flow are at a disadvantage when it is hot. The underhood of your car gets pretty hot and these intakes are forced to suck in hot air. In addition, many have found that the engine pings with these intakes. The OSCAI generally has provided better performance than these intakes. I did not have an underhood intake before the OSCAI, so perhaps someone that has had experience with both can better distinguish between the two

 

I love that sucking sound...
well...u might notice it gets dirty fast if u decided to cut ur splash guard open. I love my OSCAI though.

 

So far the OSCAI has performed up to it's billing. I've driven in heavy downpour at highway speeds with the scoop dangling lower than the splash guard and not a drop of water in the filter box. Go with it! It's cheap and just as effective if not more than what's out there.

 

my car will be lowered soon... so that might cause for a larger chance of water getting to the filter box...not sure though. thanks a lot for the help guys.
