So my car finally left its warranty period from my carmax warranty, only thing that went wrong when I had the car was Tranny once, and a motor mount.

I am at about 110k miles. Just had spark plugs replaced with OEM NGK plugs, timing belt, water pumps, accessory belts, K&N filter cleaned, Recently did a mid muffler delete as well as adding an AERO AR25 resonator and new Magnaflow race mufflers, car sounds very nice and maybe a little more torque-y.

But I was wondering what I can do for cheap or at least things that are easy. I am not very mechanically inclined, but for most things, my or my friend who is a tech at a dealer can do most things at his house.

Should I do a throttle body clean? seafoam? If I do seaform, should I have done it before i changed my plugs? If i do seafoam, should i put in the old plugs, seafoam, then put new plugs back in or does it not matter?

Car is running very well but I am thinking since I decided to keep the car, I would like to do any sort of preventative maintenance or cleaning to keep the car running tip top. Engine still strong and pulling as hard as it did when i bought it 80k miles ago.

Thanks for any input.

 

seafoam will NOT hurt your new plugs- they burn hot and thats what it takes!
its only an issue if you had 110 on the old plugs and did not do an after drive- crud will stick to the plugs

clean TB air plate, seafoam everything including oil and drive a few hundred miles to clear the oil passages before oil change

 

you may find the car runs better if you install a cover over the O2 sensor- a `spark plug anti fouler`, see threads on here about it
with increased exhaust flow- the sensor can be fooled- the shroud around the tip slows air to normal spec
