mods on 86000 miles?

Is it OK to do modifications on an engine that has 86000 miles on it? its a 98 GC 5.2. the engine is running perfectly, but who knows really. im planning to add throttle body, spacer, and air intake. will this upset my engine? my co-worker says it might kill the engine.

I started modding my engine at about 30K with a throttle body spacer that I purchased from Don A Vee. I got a cool looking blue metal spacer that did ABSOLUTELY NOTHING!

Get the intake and the exhaust or the performance computer. The TBS isn't worth your stamp on the envelope.
