pipercross vs standard air filter, fuel efficiency experiment

[mymorph]

ive decided to perform a little experiment into fuel efficiency using a new standard paper filter Vs a pipercross foam filter.

test:
an 11 mile run along m54 @65-70 mph followed by 2 mile @ 20-40mph
plan of 10x test run on each filter over the next month or two.

variables:
weather, traffic, diesal quality.
any delays etc during jouney will void that particular run.

results so far:

standard: 54.8 mpg
AVG: 54.8

pipercross: 53.2, 56.2
AVG: 54.7

will update as i get the results over the next few months.

Sounds like an interesting experiment. I cant see there being much, if any, difference between the two as the standard filter sould be morethan capable of delivering all the air required for a standard run. I think the only time you might see a diference is when driving the car hard.

i did consider/would have liked to go flat out, pedal to the metal along the m54 but thought it might raise too many eyebrows

i was hoping to get a small increase in mpg of say 2mpg with the pipercross, but we'll see. so far you couldnt get much closer.
