I have owned my 03 6MT coupe for 10k miles now, it has 82k miles now..... I was thinking of getting some maintenance work and tune up work done. Idk what all maintenance the previous guy did. Car is completely stock.

Here's the things I've already done

regular oil changes
transmission/differential fluid change
brake pads.
changed tires
did alignment
air filter


Do you think i need to change spark plug?( factory recommends change at 100k)
belts?
any other suggestions?

Also i bought a used injen CAI..... I have read through the forum, and havent gotten any concrete answers if there are gains or increased mpg, some say it works while others say it doesn't......ny insight on that.
Also is there a DIY on fitting the injen CAI without having to take out the bumper?

 

Spark plugs, brakes and belts asap. Just a start. I'm sure other members can also make suggestions. GL with your work.

 

Belts, do the plugs and check the valve cover for leaks while you're at it.

 

In-cabin micro filter

 

I read somewhere factory recommends, sparkplug change at 100k is that true?

 

Yes, for factory platinum, 100k is generally the rule of thumb. Many go less, some go more; if your MPG is suffering, it's one of the first things you can do to make it better.

You can also flush the coolant and brake fluid and add that to the list of things to do, along with what the people above said.

 

Changed mine at 90,000KM and then again at 165,000KM.

 

I would change all fluids. Nobody mentioned clutch or power steering fluid yet.

 

Here's what I did at 165,000KM if it helps any.

Change spark plugs
Change alternator Belt
Change A/C Belt
Change brake pads
Change brake rotors
Change cabin filter
Bleed/change brake fluid
Flush/change power-steering fluid
Flush/change rear-differential oil
Flush/change engine coolant
Flush/change automatic transmission oil


I get an alignment every 20,000KM regardless. Change tires and brakes when they wear.

 

Thanks all.

 

A good place to start with your mileage would be with plugs, and if you've never changed it do the radiator fluid then power steering and brake fluids. How about your cabin filter, unless your ride is garage kept those can get major stinky....G/L

at 100k miles, is it also advisable to change the pcv valve, and the fuel filter?

 

Fuel filters never need to be changed on these cars, PCV valve yes.

 

I change the spark plugs Friday, and they were in bad shape at 87k. I have a 04 and got it just over 2 months ago. You might want to check shocks, wheel bearings...

I have bad front wheel bearings, but I will replace all bearings soon. And will be changing out shocks with bilstein shocks...
