Have had my truck for a little over 4 months and am wondering if there is a specific brand of spark plug that is recommended by TTORA members. Look at my sig to see engine type and I don;t have any kind of mods soooo . . . looking for performance and efficiency. Also, are there any recommendations for any kind of stock upgrade as far as wires/plugs/oil filters etc. (normal maintenance kinds of things) Already use Mobil 1 but thats it for upgraded fluids. Like I said anything you can think of . . . looking to run this truck as long and clean as I can. Thanks a lot.
