Overview:

Holley's complete accessory systems for LT4 and LT5 applications have all accessories pulled up and in tight. Plus, they add the much needed hydraulic power steering solution. There are no shortcuts here. Holley incorporates a splined dual bearing system that eliminates all belt stresses on the P/S pump's internal bearings, assuring long life. The supercharger drive maintains the original and optimized belt path and tensioner. The accessory layout is as if the original manufacturer had designed it for your swap application. Included with each drive system is a throttle body angle correcting adapter that better positions the TB for swap applications as opposed to the aggressive original application intended angles. Versions of these accessory drives are available for both wet and dry sump applications.

Features:

  • Adds power steering without any belt load on the P/S pump
  • Notably more clearance to swap applications than other options
  • Original equipment look
  • LT4 style premium alternator
  • LT4 style water pump design
  • Compact SD7 A/C compressor

YES THEY ARE WORTH IT !
Style: 121PCS Clips with Tool for Honda/Acura
Spot on! Used it to secure my new grill and bumper for my 97 civic. Nice quality fasteners. Super cheap price. Simple enough to use and the different sizes were clutch for what I needed.

These are quality bulbs and more reliable than halogen
Size: H7
Car that I drive is a 2008 Mazda 3 4Dr Sedan Automatic i Touring. Got so tired and fed up with felt like spending money every month or so on halogen bulbs. It was always the same old story, trip to auto zone to avoid a fix it ticket. I almost tried to buy the Sylvania brand on Amazon for cheaper but what's the use? Its STILL the SAME product. I'm done with those and never going back. The new Territory Has snapped right in without any special add on adapters, just plug and play deal. Way brighter and super easy. Love them. Can see way better at night and not have to worry about them burning out so quickly anymore. More than I can say about the Sylvania brand "Made in Germany". They're slippin

I’m really happy with these lights! They were easy to set up, work perfectly, and give off a beautiful glow. The brightness is just right for creating a cozy and relaxing atmosphere without being too harsh. The quality feels great for the price, and they instantly made my space look more modern and inviting. I also appreciated how well they were packaged and how quickly they arrived. Definitely worth the purchase, and I would absolutely buy them again. Highly recommend to anyone looking for stylish and reliable lights!

Termitor H11 are so worth it
Size: H11+9005
LED Lights are as described. They fit perfect in the low beams and high beam spots. LEDs are super bright and work great at night! Soo much better than the old fluorescent bulbs that came with my rig.

Bright light
Size: 9004/HB1, Size: 9004/HB1
Keeping track of longevity. Had these bulbs for a month and will try and update if they fail. Unfortunately a while ago I hit a cow, seemed to just pop up out of nowhere, the truck was rebuilt and I wanted more/better road lighting. I am using these in a Mack truck for work so they are getting used. I run at least 10 hours a day, 5+ days a week and have at least 11k miles on them since installed. Install is just like a standard bulb no special steps needed. Produce a lot of light and good patterns on high and low beam. So far I really have only had one issue with the bulbs and that is the daylight running light/DRL operation, they don't work I believe the Mack drops the voltage to slightly dim the lights when running in DRL operation and this causes the bulbs to just intermittently flash so I just run with them on all the time. This I don't believe is the bulbs fault and is more an analog vs digital issue. Therefore I'm testing the longevity of the bulbs if my truck is running they are on. Will see how they do as the days get hotter as they are in a small sealed space.
