My BHAF was getting sorta grungy on the outside:
UGHHHHhhhh!
SO, time to see what was needed to get the intake back up to snuff.
Took off the Outerwears, revealing the underliner my wife sewed up for
me while I waited for the Outerwears to arrive - I had also applied
some K&N filter oil to that liner that was left over from my
K&N filter days:
HMMmmm - not bad, but not good either - better pull it off too, and
check out the actual NAPA BHAF filter media to see what it looks like:
WOW! Not bad at all - in fact, it looks as clean as when it came out of the original box!
OK. so a look around in the BHAF mount area turned up this surprise:
A closer look:
HMMmmmm - a contact point of wear, a "dimple" where the end of the BHAF has rubbed into the air conditioning line - not good!
Here's the correction:
Some hose split, and placed over the line to protect it - that line
also sits directly upon the inner fender well - and is exposed to point
of contact wear there as well, so the hose fix takes care of 2 points
for the price of one - sure glad I caught the problem before the A/C
line was punctured!
SO, washed both covers, and re-installed the BHAF:
Finished!
So what's the point?
Well, one point is that the Outerwears, plus the added inner lining,
can greatly provide beneficial pre-filtering for the BHAF, extending
it's service life without any detectable added airflow restriction.
Second, is that it's a good idea to check out the after effects of some
of our "shade tree re-engineering" - sometimes we just might be trading
one problem for another...
It's also worth noting that close examination of the neck area where
the BHAF attaches to the stock intake tube was showing signs of
buckling/crushing from the hose clamp - I had a short section of 4 inch
exhaust tubing I had originally picked up for reinforcement at that
point - but thought it wasn't needed due to apparent strength of the
BHAF neck - I was wrong!
