stock air intake question

i applaud your common sense, sir!

Another that Jac-Fab sells:

But it doesn't help one bit. Except to drain your wallet

Not true. The K&N filters are less restrictive so more air passes through. Also, as opposed to stock filters, K&N direct replacement filters are washable so instead of having to keep purchasing new air filters you just re-use them. In the long run, it will save you money.

It all depends on preference.

I am a big fan of OEM. The engineers whom designed it knew what they were doing, or they would have added one, at extra cost for us of course.

For the cost of a CAI for a non-racer like me, just doesn't make sense. You are getting cold air intake (CAI) relatively, compared to the heat of the engine surrounding it.

Not allowed to talk about the other after-market thingy as I am on my final warning for my humble opinion that is brilliant but not appreciated.

Peace out.

Of course. The cars come from the factory perfect in every way, with no room for improvement. Those engineers have unlimited time and budgets, and no regulations to contend with, so they've thought of everything!

Your second point (money savings) is correct.

Your first point has been proven false. The drop-in K&N filter does not increase power. Often times the OEM airbox itself is a big part of the restriction of airflow. Have you seen the snorkel that comes off of that thing?

The snorkel actually helps the stock airbox... It flows worse if you remove it.

JMO, but there were 3 things why I spent the money and bought a CAI and not in any particular order. 1. Increase in MPG. Granted it may have only been a tiny increase but every little bit helps especially when just 2 months ago we were well over $4 per gallon. 2. Performance. Again very small increase but again every little bit is appreciated. 3. Looks. This is probably one of the more important factors about adding this as to me it now looks a lot better under the hood. I bought the Injen CAI with the polished tube and it looks nice under the hood. I was going to settle for just adding the K&N filter to the air box but why not make it look cleaner under the hood.

Why would that be? How can channeling the air through that narrow tube help?

I'm just curious, as when I pulled my stock airbox out to clean a bunch of crap out of the bottom, I kind of laughed when I saw that appendage coming off of it.

The radiused entry on the end helps smooth incoming airflow, and increases velocity. The narrow tube with the radiused end, is better than a narrow hole with a flat end.



Take the test results with a grain of salt because they were not tested through a head/intake/throttle body. Just tested with the stock airbox, and stock intake tube. You're better off leaving the snorkel than you are removing it.

Wow, that's some awesome info. It leads me to a few questions/observations:

• How much different than the V6 intake box/tube is the SS intake box/tube (i.e., do you think the results would be identical)?
• Do you know if the drop-in K&N filter would increase power, since it increases airflow by 11% over stock? Everything I've read on here--and elsewhere--has said otherwise, until now. I don't want to continue to repeat bad information, as I (and at least one other person) may have already done in this thread.
• The snorkel seems to slightly help airflow, but it's help is essentially negated by having a filter in place. Is 3/4 of 1% statistically significant?

Thanks for posting your research.
