Aftermarket alternatives to maintenance items..

[Ahheck01]

Just going through all the maintenance items, I'm wondering if there are aftermarket upgrades for the following:

Thermostat
Thermostat Housing
Water Pump
Oil Filter
Fuel Filter
Fuel Pump
Spark Plugs (Bosch Supers okay?)
Airbox filter

and I'm not sure if this is the right section for it, but since I need to replace these, are there smart aftermarket replacements for:
Driveshaft
U-Joint

Thanks!

bosch supers for spark plugs
K&N filter for airbox

everything else is waste IMO

How about low temp thermostats?

I know for e36's there's a stuarts water pump - is there an equivalent for the e30?

the stock E30 stuff is fine

I would even argue that a K&N filter is a waste of money

Stock is fine, and the K&N probably doesn't do much.

There's no optional waterpump. E36's have the different pump because the stock one has plastic parts. E30's use entirely metal water pumps. And they get changed with the timing belt everything 50,000-60,000 miles anyway.

You didn't list spark plug wires, but I'm working on a way to use generic aftermarket performance wires (Accel, MSD) but retain the stock terminals and boots so they will work with the stock distributor cap. I snipped some wires at the junkyard to experiment with; I just need to find the time to look them over.

I used an msd kit from autozone, $25, rented the crimping tools there to use the ends off my old wires. Make sure you get ones that your impulse sensor will fit over if you have one.

Nice, that sounds like a good way to go. My car doesn't have the sensor, so that will make things easier.
