because the stock air cleaner doesn't flow well enough for me, and i don't want to cut holes in it since i don't plan on butchering it. also, the winter/summer flap keeps closing on me when i'm driving and it gets me al hot and bothered....

the ITG looks ok, but i'm afraid that it might have the same effect if my intake backfires. also, i don't believe that it filters as well....

I just finished watching the Ztherapy video and installing new carbs. One thing I learned is the stock air box with the integrated air horns flows as good or better than the aftermarket horns. They tested different types of brands including the ones MSA sells and found the stock unit to be superior. Bambikiller240 is correct. Regardless what you do use some type of horn or you will loose power. I use the stock unite and make plenty of power and will not ever change my set up because I do not think I will gain anything but better looks.

If your intake backfires you do not have the carbs set up right and you could eventually have an engine compartment fire, problem with the SU's. the type of filter and horns should not cause that problem the tune of the carbs is the problem. Call Ztherapy and ask them some questions about the flow and tune of the carbs and try watching their video, it is worth it.

Anybody got a nice '71 stock air cleaner for sale?

How do you like the K & N's? How hard are they to install? Here is my current setup. Works OK just doesn't look good.

I quite like the look of your setup actually :classic: . I was thinking of making a copy for mine out of an old stock air filter cover I have to go with the K&N I have just bought.

Jason,

Looks just fine! Only improvement would be a trip to the chrome plater. I also intended to do what you did but went with the round K&Ns and the TWR velocity stack (sold by MSA). As Craig mentioned, the filter element on the round K&Ns is a little difficult to install, but if you slightly squeeze it into an oval, it will slip right over the two long outer plate mounting studs and velocity stacks.....won't effect the filter element, as long as you are careful not to poke a hole in it.

K&N Filters for everything, air filter, oil filter and fuel filter. Scott even retro fitted a K&N for my vacuum cleaner and A/C unit in the house. Not really but that would be cool

Hi Vic, I once tried a K&N filter in my shorts, after a heavy dose of Mexican food, but blew the filter element right out......K&N filters are great but not impervious to really hot gas!!! If you know what I mean! Just kidding of course!

Can I ask a little side question - how often should one replace their air filter??

With K & N filters you don't replace them, you clean them, re-apply oil, and reuse.

K & N makes a great filter for the stock air cleaner can. Why start butchering OEM stock parts when there is no need?

i like my set-up just fine. flows like a champ, and you wouldn't believe the power gains over a STOCK (i mean stock air filter, too) air cleaner arse'y...

is this seat of the pants HP or actual HP from a dyno readout ? I havent seen any real numbers yet from a dyno that shows a gain from the stock air cleaner box with a K & N filter.

I agree. Seat of the pants HP can often be infuenced by the wish of more HP. Real number do not lie and I do not think the difference can be felt between the stock and not stock set ups and if it does make more power at all then I bet it is no more than 2 HP which will not be felt with the a$$ dyno.

seat of the pants, however, it REALLY can be felt. it's not just psychological, even though it sounds sooooooo good......
