What brand oxygen sensors should I go with?

should I find 703 injectors new or junkyard and clean?

When should I change my oil? Haynes says every 7,500 I've been doing 3,000 with cheap stuff. Next oil change I am switching to full synthetic with mobil 1 filter (203 filter I think it was) says its good up to 15,000miles.

I want to put in air shocks front and back any good / bad brands or suggestions? Looking for ride comfort. Plan on putting air bag system in the back for towing 3,000lb trailer plus mower, weedeater and 7 gallons of gas.

I will be towing 3,000lb trailer once a week and plan on transmission cooler. Any suggestions to brand or size?

Best brands for spark plugs, wires and distributor?

Should I replace my original front coil springs?

Does the Bishko shop manual from rock auto that much worthier than Haynes?

 

I'd find refurbished 703's. Air shocks ain't gonna improve your ride. I put them on the rear because my springs are way shot. Yea, they hold it up, but don't really provide "shock absorption". It's pretty bad on my washboard road. A buddy put air bags on his truck to deal with a huge camper. Pretty neat. It rides like stock, until the major load brings the air bags into play.

 

Going with

bosch oxygen sensors

Refurb 703 injectors

Oil change every 3500 full synthetic returning my Mobil 1 filter for napa gold / wix

Bishko manual is more comprehensive and year specific than Haynes

Maybe champion spark plugs and msd wires or just get the accel tune-up kit

Searching works

 

Still not sure if I should change my front coil springs for new

 

NTK (NGK division) O2 sensor is what I've seen mostly recommended on the Forum. I replaced a Bosch with the NTK some months ago. I cannot tell you the NTK is superior but my MPG are back to the low 20's so I'm happy.

 

Thanks for the input. Low 20s sound attractive I'm 98% city so I might not be near that but hey every little bit counts.

 

Not Bosch for O2 sensor. NTK.

NGK plugs with good wires,cap, and rotor.
