I'm a NOOb so take it easy on me ...........
Okay..... Just picked up an 05 Si... I was wondering what were the best spark plugs to put in? Factory denso? NGK Iridium? Etc?
The car is non turbo and has an aftermarket muffler is all.
Also, how do i change the fuel filter?? Where to buy it? IDK where it's located either.... lol
Thanks in advance !!

NGK iridium will do fine. Fuel filter is under the rear seats. You'll have to replace the whole assembly i believe. A little over a hudred bucks at autozone...there is a Do It Yourself for the fuel filter...

there actually is no fuel filter in these cars, there is a little sock on the bottom of the whole pump assembly and it is not part of service on these cars

Denso and NGK iridiums are equivalent OEM replacements (just make sure all 4 are the same brand). The stock heat range Denso plugs are IK20, I don't know the NGK part number but a parts shop should be able to find it for you easily enough.

ASOLUTELY FALSE ! ! !

There is indeed a fuel filter, it is integral to the fuel pump assembly that fits into the top of the fuel tank.

Here is a pic describing the general layout within the Fuel Tank cap assembly.

Here are the major parts that I have the part#'s for that are not listed in any parts breakdown. (along with a Walbro 255lph pump).

Here is the filter dissected after 140K miles or so.

Notice how it is a wrapped cardboard style filter.

Here is a pic of the fuel lift inside the filter, it was VERY dirty and gritty

It is under the rear seat, thru a access hatch.
