I'm not a big believer in K&N filters and run stock paper on my other 2 cars to keep the airflow as clean as possible, but years ago I put a K&N in the 83 and just left it there. A few months back I took it out, cleaned it, reoiled it and put it back in, so it's not like I've never ever serviced it, though.

Recently, I've been working down a list of items that might be causing this car to guzzle fuel and among several other items, I decided to replace the K&N in the stock air box with a Mahle paper filter.

Stuck in traffic with the A/C on today I noticed that the car was running unusually hot. Perhaps hotter than it did with the K&N. I wonder if this is actually the case, since the K&N is designed for greater airflow than paper filters?

 

Probably not.

 

M758.....Grats on the nuptials! But how is it you can post while "honeymooning"!? You need to get "buzy"!

Perhaps the A/C fan is not kicking in so you are running hotter. Did you hear the fan when the A/C was turned on? Dal

 

Dal,
Thanks, Not honeymooing yet however.

I will be leaving Friday Morning!

 

I assume you're running a K&N in the stock airbox? Hard to compare on two different days, unless the conditions are identical. I find it hard to believe a filter element would do that. I run K&N in stock box and clean it every year. Been running one on my Norton for 15 years now, it still looks fine.

 

It's must be a coincidence Luis. Even if your new paper filter were somehow defective and starving the engine of air, I just can't connect that to overheating. Since the AF is upstream of the air flow meter, a clogged filter should not cause rich running (which I don't think would cause overheating anyway). A lack of power pwerhaps... But at idle in traffic? Air demand is low so it's difficult to imagine it starving for air. Just my 2c...

 

Thanks guys. I guess it's time to replace the coolant, then. And Peckster, this car is in the Caribbean where day to day temperatures are practically identical ~85 deg F.
