well, im planning on taking my gxl out to a close by rotory shop to do a full tuneup... what i want to know is, what kind of brand should i use for all the fuids, sparkplugs, ignition wires, and should i upgrade to larger injectors?

 

The stock injectors are probably fine for anything but heavily modded engines. Wouldn't hurt to have them professionally cleaneed and flowed.
I've used Neo and Redline synthetic xmission oil and rear end oil and they've both been excellent. As for the plugs, just go with standard NKG's . Plug wires..I would replace the stock ones with a good quality 8-8.5mm set....just my $0.02

 

thanks for the info
