| If you have a '99 or newer car, your
stock airbox can be made to be quite efficient, with a
K&N factory replacement filter. Taking the box out,
and removing all the restrictive walls is the most
inexpensive way of upgrading your intake. K&N part
#33-2141. This part also works on 97+ models. The K&N
replacement will work, no matter if you "gut"
the air box or not. |

|
| Next level is to buy parts to install a
free flow "cone" filter, after removing your
factory airbox. Pictured here is a K&N #RE0870,
mounted right to the factory F-Duct(no extra parts
needed). If you would like to clean it up, parts include,
1- 3" Rubber coupling, 1-3" Street 45* bend.
Don't forget a way to drill the new parts to insert the
AIT sensor. I just drilled mine, just big enough to hold
the sensor. Most people buy a grommet, and drill for
that. |

|
| 3rd option is to house the freeflow
filter in a "Cold Air Box". Here is an example
of a homemade box. It isolates the filter from the engine
heat, and gathers air from the fender well, and the
headlight housing. The easiest way to do this is to cut
up a a cardboard box, and use the cardboard to make
templates. After which you will cut the plexiglass
accordingly. |
 |
|
| 4th option is to build a "FWI",
or Fender Well Intake. This requires a bit of
manipulating the fender brace, but produces a nice clean
looking intake. Here member Ron, has used the stock
F-Duct, a 16" piece of 3"PVC painted to match
engine bay, going to (not seen, a rubber coupler going to
a 3" street 90*, going to a K&N RE0870) |
 |
|
| Last but not least, the most expensive,
but the most professional looking way to upgrade your
intake is to buy a kit online. This is a picture of a
"Thrasher" CAI. There are many other options
besides Thrasher, and all of the kits can be found at all
the stores GP parts are sold. There is always controversy
as to which is the best...Bottom line is, they all are
effective. You install what you think looks good. |
