CAI Are Bad News!!!!!!!!

So I read on another forum that someone had a bad experience with a cold air intake and frying his engine. Basically the filter didnt filter very good and ruined his engine by letting continuous small particles go into his engine. He even had a sock on the filter as well. He had an AFE CAI with pro dry filter.

Im worried. Maybe you should be too.

 

OOOOOOooooooooOOOoOO im scurred. Just think how much damage those particles are doing. Well i just installed my Afe maybe 2.5k miles ago if someone wants to buy.

 

this seems like it should be a filter issue more than anything else, I dont really see what the CAI would be doing wrong if debris is getting past the filter. Taking in a few more particles? maybe, but if they are getting past the filter then i feel like there is a larger issue than where the air is coming from

 

Idk if i can post up another website but anyways. Basically cai companies are trying to get the most flow of air with some filteration. But toyota is more worried about filtration. What i mean is the dust IS getting through the filter.

 

quick google search and you should find it

 

Im about to sell my Cai right now and buy a muffler lol

 

Old news.
Go search on Tundrasolutions back in 2004 for "Cylinder scoring + K&N"

 

Nothing filters better than a properly oiled filter. What kind of filter was he using?

 

+1

K&N , AFE, and other racing filters are shit for filtration and absolutely will lead to cylinder scoring.

 

Your wrong

 

No he's not.

Nothing filters better than OEM paper.
Other filters may flow better, but OEM paper flows more than enough for any normally aspirated engine.

 

I'm pretty butt hurt about that haha how was it if I didn't work I would of gone

 

Dang looks good

 

Actually some guy on the net reviewed some filters and found that Napa Gold filters the best. Its a give and take want more airflow? You will get less filtration.

 

I'd like to know what their take on it is. Not a bunch of people who have read forum after forum. I've been running CAI's on all my vehicles for as long as I've been driving. My Tacoma has 120k now and runs perfect. It's had one on since I purchased it new. Rousch, Steeda, Whipple, etc. all run CAI's on superchargers. Granted these aren't supposed to run for 200k miles, but they are choosing performance over longevity.

I agree that low filtration can cause scoring of the cylinders, but more common scoring issues are caused by poor oil/fuel mixture and the oil itself.

I think that the level of particulates between OEM paper and aftermarket CAI we're talking about here is negligible over the life of the vehicle if the CAI is properly maintained.

Here is Bob the Oil guy's take on it:

I agree with his comment at the end, you can either have great filtration or great flow...not both. For me, I'll take air flow over filtration.

 

Thanks for the link. That was some great info...I had no idea

 

This is correct. I use Napa Gold or Wix. Both made by Wix. K&N type filters got their reputation as being good filters from offroad racing. They would continue to filter and deliver good power long after paper filters had choked off the intake. Race engines however have no need for long term engine protection, so the fines that get by are of no consequence.

The imagined performance gains on a stock vehicle are the product of placebo effect and increased intake noise.

 

Yeah, you don't really get any power gains from CAI's. Just more noise. I'm a member on the LXForums because we own a Charger SRT8 and they did an extensive CAI review. Basically, they went to the track and ran 1/4 mile times on a variety of aftermarkets vs. stock and also ran dyno's on them. The results are here:

In the end some picked up at the most 4 - 8 hp and when you're talking about a vehicle that is rated at 425hp at the crank, you're looking at a 1 - 2% gain in HP which in reality won't even be felt by the end user.

I run them on all my vehilces because I like the way they sound, how they unclutter the engine bay and the fact that I can wash my filters instead of purchasing new ones every 5-10k miles.

 

Yep, the few times when the dyno spits out a couple percent gain it is always at an RPM where nobody drives.

The reasons you stated for having a CAI are all honest.

I have both ambient air temp and intakes air temp (via the Scangauge). I can compare them real time, and the difference between them is rarely more that 2 degrees. The factory intake is already a CAI! You aren't going to get any colder unless you have a cold can. Most likely the aftermarket CAIs are actually delivering warmer air, not colder.
