"Item came on time and as expected."
"He likewise walked me through the install (very helpful, but obviously tired and frustrated by his tech support position, and that came through in his tone). So I uninstalled the unit, which is supposed to reset the vehicle to the factory settings as downloaded to the sim card (maybe in this case), boxed it up and returned it. The shop has one of the best ODBII commercial reader programmers (just over $8,000) and he said the Bully Dog has left the computer in a locked state, and he cannot push changes to the vehicle. I'll take his report and contact Bully Dog in hopes they will help me get back to the known factory state as prior to installing their tool and device."

Best Automotive Performance Igniters

PerTronix 1281 Ignitor for Ford 8 Cylinder
The Ignitor has been called the stealth ignition because of its quick installation and nearly undetectable presence under your distributor cap. Rotating cobalt magnets trigger a Hall Effect integrated circuit no points to burn, no moving parts to wear out.
"Some people report that they were able to just hook it to the factory wiring (pink resistor wire) that connects to the + side of the coil."
"I installed this in my 1966 Ford Thunderbird due to the previous owner thinking that the car had a reverse ground, when trying to start the car the original ignitor had failed."
"#3: NEVER leave your IGNITION SWITCH ON without starting the car..It will burn out the Module . It is like leaving the ignition Switch in the ON position when you have the POINTS and CONDENSER SYSTEM in the car."
"had for a few months now...works great as far as i can tell."
"Replaced a worn out set of points."
"This time I tried to use it on a 289 Ford V8 the magnetic pickup was too loose on the distributor shaft and therefore would not work."
"waste of money."

Delivers more torque quicker starts instant throttle response better acceleration a smoother idle and improved gas mileage.
"I was apprehensive about purchasing these because they were fairly cheap compaired to those at the local parts stores. PROBLEM: I noticed a jumping/hesitation whenever I put the truck under any load (hills, passing, towing). Initially thought my transmission was slipping but did my research on the F-150 forums and also talking to several mechanics. The dealer was going to charge me over $700 to diagnose which coil pack was bad and replace it. FYI...remove the module and bracket on the left side of the engine for easier access to the two rear packs."
"While they worked fine I think I am going to go back with the motorcraft ones because I can get them at a similar price and the old motorcraft ones were still working with no problem at 80,000 miles."
"You should also consider the OTC 6900 Ford Spark Plug Socket and the broken plug remover kit just in case."
"Put an old stock coil back on ( yes, I saved them) but still had a bit of a miss. I used to be a big fan of Accel, Mallory, MSD years ago on lots or cars. I sure didn't expect to be revisiting coil issues in twenty thousand miles."
"Now I get to go and dig through the garage to find the old coils so I can take these low life coils off and replace them with the superior, and might I say cheaper coils I originally had in the first place."
"So, rather than pay a shop to diagnose which one or ones that failed I purchased a cheaper set of Bravex ignition coils for $50 and they are warranted for 2yrs."

Best Automotive Performance Electrical Accessories

HELLA 003399803 Supertone 12V High Tone/Low Tone Twin Horn Kit
From the first electrical headlamp to theintroduction of Xenon headlamps, Hella has led the way in automotive lighting and accessory development for over 100 years--a legacy that continues today with the Hella Supertone Horn. At the 24 Hours of Le Mans, Rolex 24 Hours of Daytona, 12 Hours of Sebring, and the Baja 1000, being able to see during the night is the difference between winning and losing. Rock falls, extreme humidity, or even the effects of mud can cause problems with functionality or cause failures with lesser lamps. Their stability, durability and outstanding lighting performance have been legendary for years, yet they have been subject to constant ongoing development. Technical Specifications Sound Level: 118dB High Tone Frequency: 500Hz Low Tone Frequency: 300Hz Voltage: 12V DC Power Consumption: 66W Current Draw: 5.5A @ 12V (each) Diameter: 123mm Terminal Contacts: Blade Type Mounting Type: Single Screw Weather Protection: Teflon seal. Loud and powerful dual super tone horns add a level of safety to your driving with 118db(a) of sound.
"Other than buying factory replacement horns for a vehicle whose horn sound you like, buying horns based on an expectation of a certain sound or tone is actually quite difficult. They really sound like Mercedes Benz horns from the 1970s - early 2000s. Also note that these horns are actually quite large and may not fit where thd original horn was mounted. Fabricating mounts and installing all wiring to and from the horns and relay took a few more hours. Hella Relay Wiring Instructions: These instructions are for vehicles where the horn button supplies power to the horn when depressed and the ground is constant. Terminal 85: chassis ground. Terminal 86: intermittent positive lead FROM steering wheel horn button TO original horn. Terminal 87: output TO new horns. Terminal 30: 12v constant with fuse 15A. Please Let me know if this review helps."
"This setup is for Subaru XV Crosstrek/ Impreza 2015 or older. ITEMS YOU NEED:Get it from Autozone."
"They do not sound stock, they sound a touch on the aggressive road rage side I work in a Bodyshop so I replace horns on all types of makes and models when they're recked and these are hands down louder then pretty much anything coming factory on ANY car ."
"Like most men, I think a car can never have too much horsepower, a bank account can never be too big, and a horn can never be too loud. If you want a loud, nice-sounding horn, try some Fiamm Freeway blasters."
"Be forewarned, while these horns aren't the loudest ones on the market, they are pretty loud and a great upgrade over my stock horn and I've scared a person or two before. So far I've had no issues with anything electrical and the horns work and sound great."
"****DO NOT REMOVE THE BRACKETS FROM THE HORNS***** Unless you have an aftermarket bracket that instructs you to remove the hella brackets do not remove the brackets or they will sound terrible and vibrate anything touching them."
"They look great, sound great, and installation was as easy as cake with the included mounting bracket."
