How do I get NOX lowered to pass emissions after fuel injector fluid made NOX go up very high?..Retest cold engine for NOX?..Should I change oil first? Sorry I should have said questions.

Your higher NOX levels will probably return to their previous levels after you burn through this tank of gas. In one of your other posts, you stated that you had gotten the NOX levels down to 1147. What level is passing in your state?
In the above mentioned post, you can see there are quite a few things that can cause high NOX levels. Getting your codes read is the first thing you should do. In your first thread, you said you have a '91 Cherokee, and that your "key switch doesnt blink", which sounds like your Check Engine Light (CEL) might be malfunctioning. Do you have an AutoZone nearby? I believe they'll check the codes for free at most of their locations.

Why am I different?
Looking at a new air intake I just noticed that my stock setup seems to be different from anything else I can find on the web.
What's up with the second airbox on top of the throttle body? Anyone know what it's for? Says Chrysler on it so I guess it should have come with the car.

I had a JVC in an old truck of mine. I only spent about $100, had a pre-amp output on it. I ran it to 2 sets of components, and to a cheap amp & sub setup.. It did me fine for 4+ years until I sold the truck. If it suits your needs and the price is right, I say go for it!

I replaced the rear main oil seal and this was attached to the two rear oil pan 5/16 bolts. It faces the transmission inspection plate. Where can I find a new one, what is it called, or do I even need one. 2001 XJ auto 4.0 stock

Ahem, so they basically put a muffler on my intake system?
I'm in Sweden yes.
My thought is it must act as sort of an air heater since it's right on top of the engine. Which makes little sense seeing how crowded and hot the engine compartment is even without it.
I'm going to have a look inside to see what's in there.
Thanks,
D

no, it's to quiet down the intake noise. EU countries are weird with their requirements for that stuff. The only thing you'll find in there is maybe some baffles.
So yes, it's basically a muffler for the intake system.
