ARP 2504202 Stud Kit
Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned, something that won't happen with inferior quality head studs. ARP studs are thread rolled after heat treat, which gives them about 1000 Percent (that's ten times) better fatigue strength than those studs that are threaded prior to heat treat. This procedure (done only to the shorter studs) more equalizes the "stretch" of both studs, which makes for a more consistent clamping force and one that compensates for head gasket compression when the cylinder heads are installed. Thread Rolled After Heat Treat, Which Gives Them About Ten Times Better Fatigue Strength Than Those Studs That Are Threaded Prior To Heat Treat.
Reviews
"With the problems that plague the Ford 6.0L diesel power plant, when it came time to repair the inevitable head gasket failure, installing these ARP head studs was an absolute necessity."
"This product is the reason why many of the 6.0L trucks are still on the road."
"I did remove cab and heads and had the heads checked."
"A must for the Powerstroke 6.0."

Fumoto F-106N Engine Oil Drain Valve
Incorporating Fumoto's most compact ball valve, Fumoto's FN series valves are designed to fit cars, light trucks, vans and select commercial engines. Ideal for drawing small sample of oil for oil analysis.
Reviews
"On the 2001 Suburban [with a 5.3 liter V8], the threads on the oil drain required adding an extra gasket so the Qwik Valve would be oriented with it's release tab away from the ground. [see pics for right and wrong orientations; pix are from a '95 Saab 9000 Aero] If you prefer a longer, brass adapter for the Suburban, there is one available: Fumoto Valve Adapter ADP-107 (12mm-1.75) The Quik Valve folks are aware of potential issues with low ground clearance, especially if you're off-roading or four wheeling, so they do sell a clip that provides an extra measure of 'lock' on the tab to keep it from pivoting open if you snag a branch, etc. You simply reach the small locking tab, pivot it up slightly, then rotate it toward the drain port [approx 90 degrees] and the oil will flow. This is not a factor with the QuikValve fitting: when you rotate the tab, the brass and stainless steel sleeve pivots [looks like it's inside a nylon bushing] to open a good sized hole, approx 5/16"."
"To general a fit, should be model specific because of oil pan clearances."
"I had the last oil change service install it instead of putting the plug back in."
"Why vehicles don't come standard with oil drain valves like this, I'll never understand."
"Perfect for diy oil changes such as myself."
"Great little thing."
"After all the oil has drained, move the lever back and your done."
"Makes changing oil so easy!"

Fumoto F-108 Engine Oil Drain Valve
It is also ideal for drawing small sample of oil for oil analysis.
Reviews
"The valve had a slow leak initially, until I discovered it was my mistake of only hand tightening the valve."
"Great valve!"
"Best accessory for those that do their own oil changes."
"As long as you don't purchase the one with the long nipple it won't hang down much further then the underbody trays."
"Make sure to use provided washer not the OEM."
"I've been reading about these for 15 years it seems, but never felt the convenience justified the price."
"On my Subaru, the only way to remove the drain plug without drenching your arm in oil; is to remove it from the top."
"Buy these for every car you own !!"

Reviews
"Just what every guy or gal needs that has a Chrysler with a HEMI ...was surprised when checking the oil and washer fluid a couple of weeks ago there was just this annoying cap on dip stick tube that said FOR DEALER USE ONLY ...called dealer and can understand they want to make sure you only add OEM fluid as not to void warranty ... heck all I wanted to do was check my fluid level and they wanted me to make an appointment to come in and charge me $49.50 ...no way ... fit perfectly and if and when I need to add proper OEM fluid I will do it myself ... highly recommend and everyone should own a HEMI at least once if or not more times in their life."
"Nice to know the fluid level without having to go to the dealer...Due to it's "newness" the knob was a bit stiff to fully insert in the fill tube where it would lock in place, even with lubricating the "O" ring on the knob."
"simple instructions and easy installation."
"Internet forums are evenly divided on the accuracy vs the factory tool."
"love being able to check my tranny fluid instead of bringing it to a dealer."
"Fits 2013 Dodge charger 5.7."
"Nice item, exact fit, excellent quality."
