I couldn't find a note on filters so here goes.
I am interested in buying an aftermarket performance air filter
for the Marcos. I already have one of those poxy little chrome jobs
which is worse than useless, because it rattles against the bonnet
and is cracking the gelcoat.
Since I plan to sort out the gelcoat problem and get the car resprayed
soon it seems to me to be the time to get a filter which won't damage
the bodywork.
Size is really the biggest restriction I've got here, but assuming
I have a choice which are better the K&N paper filters or the
Pipercross foam type? Has anyone got experience of using these filters
and do they last as well as the manufacturers claim? �25 is a lot
for a filter that will only last a year or two.
Thanks,
Mark

Since this topic is on performance air filters, I would like to share
my experience in boosting my 10 year old Ford Laser(Mazda 323).
First of all, I managed to swap my standard exhaust with my colleague's
Janspeed exhaust(cost about 800 bucks Singapore when new) when he sold
his Laser Sports. I was doing at most 2000 revs at 70 kmph - awfully
slow and consumption was about 450 km for a full tank of unleaded 92
RON. With the "new" exhaust, I was able to do 2500 revs at 110 kmph.
I supposed the improvement was due to the free-flow concept of the
Janspeed exhaust.
Then I changed the standard and bulky air filter assembly for a K&N
filter with breather unit. The money was well spent. There was more air
input though noisy at times. The CO level was 0.4%. The specs for the
laser gave 0.5% - 1.5% for CO level. I am currently able to hit 120
kmph at 3500 revs. My consumption figure? I am able to get 510 km for
the same tankful of petrol.
The K&N filter probably allows more air into the combustion chambers
thereby giving better and more complete combustion which leads to
better power, mileage etc..Good air input at the filter end and good
output at the exhaust end.
