Air Filter Change Walthrough For 2007 Is250

[is200 Newbie]

I have attached pictures to this post but don't know how they will turn out....

Sorry - pictures a bit naff but can be resized by clicking on them - haven't mastered how to upload them to the forum yet.

I cleaned my air filter today - I have a K&N oiled one and tend to clean it twice a year (every 6 months) - once in the summer as I find the filter sucks up all the dust from the road and leaf bits etc and once in the winter. To be honest the summer clean is needed as it gets quite dirty but with the winter one its quite clean with only a few specs of dirt which I think is from the wet weather.

Anyway - I have cleaned it today - removed / re-oiled and replaced.

Below is a walkthrough on how to do it - although mine is a K&N it will be the same process for a stock filter (I have not shown the re-oiling process for the K&N filter)

Take off the 5 press studs on the engine cover ringed in the picture and you will need a pozi screw driver to release the screw indicated by the arrow

The last locator stud which is attached to this cover is located in the part of the cover that is tucked under the front radiator cover - lift the front cover gently and lift out the stud from the hole in the body. The cover should now come off by lifting it up.

The picture below shows the engine minus the cover required to be removed before taking the air filter out. The arrow indicates the front cover area that needs lifting slightly to remove this cover and the circled parts are what need to be removed in the next process

Next - unclip 4 catches around the air box. Slacken the screw on the rubber air hose (no need to remove screw) and also unplug the air sensor off the box. The air box clip under the front cover will be a bit awkward as it should lift up which is the opposite to the others.

Below is a picture of the air sensor and how to remove it

Press gently on the small lever (arrowed) while pulling it off the connector at the same time - it should slide off quite easy

The filter can now be removed - pictured below is a K&N oiled one.

The picture below shows the air box minus the filter - its a good time now to clean around all the fuse boxes and wiring

At this point you can also see the left bank of 3 spark plugs that you can get to in a future job in changing the spark plugs - it does not look to difficult to do although reports on the forum have reported that is a bit of a b*&ch to do?

I have arrowed the plugs on this bank that you would need to get to ...

This last picture is of the clean filter after applying the cleaning solution and drying it before adding the oil - before the clean it was hard to see through it but it didn't seem that dirty - now its clean and a lot of light can be seen shining through as per the picture.

Fitting of the filter is the reverse to taking it out.
