doesnt matter at all. you can run them forever. they're self cleaning.
besides, you're gonna need a left handed ratchet anyway. those are expensive.

I'm always amazed at how much I can pick up here. Hatterasguy is a real inspiration. I'm going right out to put night air in my tires. Get better mileage.

night air? NIGHT AIR ...someone gave you a line of crap. You only need to change the air twice a year. winter air when you winterize it, and summer air in the spring

I must disagree on the spark plug selection...... Only i-rookie-em sparks plugs should be used on a 603....... And yes, you must use a very rare left-hand ratchet......

Don't forget to clean the afterburner nozzles at the turbo.... Without those, your exhaust gasses won't exit the turbo at high enough velocities and hurt your power output!

Oh and btw when you change ur plugs on ur 603, u may want to get an MSd coil for it, and make sure to install the plugs with a METRIC adjustible crecent wrench, and while ur at the store for the coil, ask the guy if he stocks pistons for an RX7 and make sure to pick up some piston return springs too :-D

while your there for some RX7 pistons dont forget new wrist pins and why not upgrade to the Rearden Metal versions.. I hear they are the best.. John Galt said so

Thanks, guys! I almost forgot to call and get a price on a radiator for my Super Beetle, but all this talk of parts jogged my memory.

You ought to check your vacuum every now and then. Use synthetic vaccum if you want your actuators to last. What brand turn signal fluid do you use?

Wow that's a fantastic investment with a 710% cap! Is it an Autozone?

I wouldn't joke about this anymore, some newer Merc's actually, honestly have 'muffler bearings'.

They're hard to find, dude. AutoZone just laughs at you if you ask. I got the last laugh, though -- ordered me 20 of them here (just in case):

OMG I never cleaned the afterburner nozzle!

Whats the best carb to use if I want more power? Holley maybe?
