I bought a 1993 ford f250 7.3l idi turbo diesel about 2 years ago and have had troubles finding upgrades but these sound like very good, and cheap upgrades. It has loads of power, I gunned it and made the rear tire spin in on its self. The inner wall spun loose from the outer tread wall. The tires were 2 years old and the glue could have worn down but i say its cause of the power.

Turbo Taylor, Welcome to the Forum.
I don't suppose you took a picture of that stripped tire. It sounds like a picture worth framing.

Hope this picture helps identify the blocked fuel return on the stock fuel filter.

thanks for the welcoming. I wish i had taken a few pictures of the tire, i would need to tear the tire up more though cause it was just a small tear but you could tell the tire wrinkled from the torque. Also it just never crossed my mind to take any pictures.

I was looking to buy a new exhaust system and came across this Hypermax - Product Display . Anyone run a hypermax exhaust or ever heard of this brand exhaust company?

I think K&N makes a cold air intake for the turbo IDI but I cant seem to find part no. ---- Try spectre at SFX Performance Parts and Auto Accessories - Est 1997 thay have lots of intake pipe, take a look at their 4" aluminum tubing and silicone hose parts........ Also try Intercooler Pipe Fabrication - Silicone Intake Systems Auto Parts

How 'bout air filters. We have sportfisherman boats. All are equipped with Cummins 5.9 diesels and one with Detroits.
We use two things on all including my 94 F-250 diesel.
We use K&N air filters, and Delo 400 15-40 oil. Why do we do this? Because we can't find anything better. The filters are cleanable. A kit comes with their soap and an oil that gets added afterwards. I've got the same air filter on going on three years, and it's like new
Try them people, you won't be dissapointed, and you won't be buying air filters any more.
