I may try a K&N anyways...anything to improve gas mileage is good!
I know in the future this muffler is going to need a replacement. Kinda sounds a bit thin in there and well rusted towards the center, but not all the way through..yet...
Cat still looks good..sure don't want to replace it!
Before I comment on this I'll say I'd leave the TB screen in, as Mike said that topic has been beaten to death, I have seen debates on it on a few forums, most lean towards suggesting it be left in, at least from what I have read.
IMO I'd only consider the K&N filter if you go with a CAI setup, that way at least the filter is a bit further downwind of the MAF, I do believe the particulate matter you speak of can contaminate the MAF, more so if you have a lot of humid/rainy weather.
My car ran fine for years without me ever cleaning the MAF, but within two years of using the K&N filter my MAF was reading a bit off, it was not off by much, but enough to cause misfires at idle.
I tried cleaning the MAF with MAF cleaner to no avail, and even carefully used carb cleaner on the thermistors, that did not help either.
So I went with a new MAF, and a Purolator Premium Plus Air Filter, and have had no issues since.
I cannot say for sure the MAF was ruined by the oil particulates, I know I never over oiled it..
My MAF may have just failed coincidentally, but I still recommend not going with the K&N unless you go with a CAI, and even then be sure to clean the MAF each time you clean/re-oil the filter.
