Basic Maintenance
 

What kind of air filter do you suggest friends? Original, mann or other?...

I've eared that the 986 S doesen't have a fuel filter (to change), did you know something about it? It's correct?
If so in a basic manteinance about filters i've to change "only" air, cabin and oil filter?
Thank you in advance

The fuel filter thing is model year specific. Earlier cars like my 2000 have an inline filter in the centre tunnel under the car that is part of the maintenance schedule.
Later models have a permanent filter in the fuel tank.

We use Wix/NAPA Gold for all filters; better made and finer filtration than factory or Mann.

How can I understand if mine (october 1999 - 986 S) has inline filter in the centre tunnel or a permanent filter in the fuel tank...
Thank you in advance

Yours is under the car. You will need to pull the covers off before you will be able to see it. Be careful jacking the car up and only use good jack stands to hold the car up. If you are going to work on the car yourself, I would suggest that you buy a copy of the Bentley Manual for Boxsters 1997-2004. I have found it very helpful.

Truth
 

This all I use in all our automobiles

My 2001 S has an inline fuel filter located about in the middle of the car. I changed mine this summer. They changed things in 2002 to a "permanent" one inside the gas tank.

The procedure for the early one is detailed in the 101 Projects book, or you can find it on the Pelican website here:

Be careful when removing the old filter - it's quite large and holds a lot of fuel. Be sure to have something ready to catch the fuel. More will pour out as you remove it (you have to tilt it vertically to get it out...

Also be careful how you have the car jacked up. I jacked my car up and then set it down on tall ramps (too tall to drive onto). I trust ramps more than I trust jacks or jack stands. And chock the front wheels. You'll be under there for a while, so make sure the car can't fall on you.
