Change 2003 Toyota Corolla LE Engine Air Filter

Since I changed the in cabin air filter, it make no sense not to replace the engine air filter too. So I take a look at the engine air filter, and sure enough, it is hell of dirty too. Time to swap a new one! I went out and bought the Purolator A25463 Classic Air Filter (or if you like, you can get the OEM part that looks exactly like the genuine Toyota filter)

Old vs. New

It is quite easy to get to the air intake housing. To open up the box , you only need to release the two latches shown in the picture

Open it up. You want to first remove the filter and check (also clean) any dust and debris under the old filter.  

Line up the lower left corner of the filter with the box and put the new filter in. There is only one way to fit it in so you don't have to worry about any mistake. 

Close it up. And that is it! 

After couple weeks with the new air filter, I am happy to report that I observed zero performance improvement and absolutely no benefit on the gas mileage! Yeah! 

But hey, the "feel good" factor is still price less :)

2003 Corolla LE change in cabin air filter, get some fresh air inside!

I have sinus problem. I have frequent nasal congestion. I also sneeze a lot, and I notice the problem seem to worse when I am in my car. It made me think the air wasn't too clean in the car. That made me thinking about ways to improve air quality in the car. I have 2003 Toyota Corolla LE. An old car but still runs great.

With a bit of Googling, I realize how easy it is to replace the in-cabin air filter. So I went out and got this Purolator C35491 BreatheEASY Cabin Air Filter

Here is what I did: First, open up the glove compartment and unscrew the hinge on the right side

Press on both side of the glove box to "release" the tabs that are holding the glove box in place

After that, the glove box should come off easily. The air filter cover should now be exposed and easily accessible. Press on the clip at both end of the air filter cover

Remove the cover. Now you can pull out and and replace the in-cabin air filter. Put everything back together and you are good to go! 

Just thought I would give you a bit of motivation to take some action: This is the old air filter I pulled out of my car. Yes, OMFG! 

After I replace the filter, I notice I don't sneeze in my car anymore. And I am not sure if it is related, but I no longer smell that weird order after I turn on the A/C. 

So people, please check your air filter to see if it needs to be replaced. It is very cheap and very easy to do!
