I'm fairly new to owning my 240, and wanted to know if some one can recommend the best spark plugs and fuel injector cleaner to use it's totally stock with no high performance parts.

NGK spark plugs. Don't matter which, just use NGK.

Fuel injector cleaner, I've had great success with Greased Lightning's Fuel system cleaner. I've used redline, elf, chevron, and other crap that didn't do jack. But the Greased Lightning actually makes a difference just right off the bat. Good stuff. Chevron's a good additive to other brands of gasoline other than Chevron's gas and works quite well with Chevron's gas as well. Redline I was rather unimpressed with. Elf was too expensive and yielded too little bang for the buck, not to mention pretty hard to find. The others I've tried aren't worth mentioning.

Seafoam is a good cleaner through the vac lines. As a fuel system cleaner, I've seen better.
