Technical support and customer service for in house designed and fabricated products is sub par. Better hope your part isn t discontinued by them because they offer no support or backing of their product if that is the case. Look elsewhere. Should have gone with cordes performance.

Their LS 103mm throttle bodies are claimed to fit factory and aftermarket intakes. I have an LS7 with an MSD intake (the most common aftermarket) and it does not come close to fitting. The bolt holes are too high for the gasket to seal properly so you don t have a good gasket seal, there is a vacuum leak, and what I can only assume would be a massive amount of turbulence. Theirs is the exact same throttlebody as the Summit 103mm option - which has atrocious reviews regarding same fitment issue, so they are both just brand labeled for specific retailers by the same foreign manufacturer. The bolt holes on the throttlebody are also massive, like almost 1/2 which is sloppy. Two stars because they were initially communicating with me to try and get it resolved. We also mocked it up on a fast 102 aftermarket intake manifold, and the fitment was poor as well. Now I have a black anodized $650 paperweight, so I guess it s a conversation piece at least. Order a NW 103 and it fits perfectly like it should for only $40 more. Problem is, I drove with this on my Corvette for several thousand miles and could never get my idle correct - always seemed like there was some unmetered air causing us problems. Well, we discovered the issue after we spent countless hours chasing down other ghosts. Who would have thought that it was throttlebody fitment to begin with? From the outside, it looks perfect.

I recently received my Granatelli motor sports Ignition coils and wires, and I have to say, I'm really impressed.The coils are of the highest voltage on the market, and the Zero ohm wires make them perfect for high-performance applications. They also come with a warranty that is amazing.I love the look of these coils and wires. They are American-made, which is great news, and they look great in any car. The installation process was easy and straightforward, and I was up and running in no time.Overall, I'm very happy with my purchase from Granatelli motor sports. I highly recommend their products to anyone looking for high-quality coils and wires that come with a warranty.

I ordered some spark plug wires for my vehicle through this company and it was a bad experience! The website stated that they were in stock when in fact they were not in stock. I had to wait extra time to get them. Also upon first looking at the wires they looked and felt cheaply made. The wires I had on my vehicle prior to Granatelli are a lot less in price and are by far made way better and perform better. The Granatelli wires didn't even come with heat shields and the wires were pretty much all too short in length. When I say short I mean they were hugging my cast iron manifold! The boots of these wires are attached poorly also. I attempted to remove the Granatelli wires after getting a misfire going down the road and upon pulling them off the insides of the boots came apart. My NGK wires have never come apart had a loose fit or caused a misfire EVER! Yes, I know how to properly replace/remove spark plug wires. I spoke with someone at Granatelli in regards to my issues with the wires and I was told that they would compare these wires to the Motorcraft wires that came on my vehicle and send me pictures. Well, what do you know no one did that. Why? Because Granatelli isn't up to par with the factory wires. I also had to pay the shipping cost to send them back and a restocking fee. Based on my experience with this company I cannot recommend them nor will I ever do business with them again. Granatelli you may want to take lessons from NGK on how to make and manufacture quality OEM spark plug wires.

Great people who are helping auto enthusiasts maximize the power performance potential of your vehicle. Awesome place. The Granatelli name goes way back in automotive racing history. They are professionals who have the experience, knowledge, and tools necessary to turn that vehicle into a monster. These Guys know their stuff!!!

2010 SS Camaro- Jojo and the team really took care of me. Aside being a trusted name in performance. It is very easy to see why they are one of the best. From start to finish - small or large, you get honest answers as to what is viable for your particular performance need. I am BEYOND happy with the coils, intake (and a few other parts) purchased here. I will definitely be coming back soon for a few more!Product: 5 starsService: 5 starsQuality: 5 starsOverall: 5 starsI highly recommend this place!

Horrible service and product knowledge. I purchased a new set of their LS billet valve covers from a private party and wanted to install them with new gaskets since they were a couple years old. Called and spoke to a "tech" on the phone. He said they dont carry the o'ring material but told me to get a 3mm oring that was 5' long to do both the covers and I would have extra. After ordering it from an o'ring supplier and trying to install it, its too short. Called them back to try and get a solution and was told a manager would have to call me back. After waiting 3 business days and no response, I called back. The manager told me they no longer make these parts and didnt know it was even on their website. I offered to buy new bolts and gaskets for the bolts and for them to throw in the oring, nope. Literally would not do anything to resolve their mistake. If they cant provide a solution to a simple $20 mistake and stand behind what they say, god forbid they really screwed something up. They will most definitely leave you out to dry and not be there if you need them.

Bought a set of LS series coil pack for my Vette. One died after 2 years. I contacted the company and even though the warranty had expired, they are going to send a replacement as they stand by their product. Thank you JoJo for your help!

Wires from Granatelli gave me 16 more horsepower and I've never had a bad experience there. In fact I liked and trusted Granatelli so much I sold my 97 custom Softail Harley and had Granatelli install TwinTurbo's. Next I had Granatelli install there 1g suspension and that gave me a much greater cornering. In the past few years I've had dozens of my friends family and coworkers go to Granatelli most who are cops and firemen. No complaints about price and we all know you get what you pay for so we never go bottom bed. Granatelli gives you a lot of top quality equipment for your money. And I'm not rich but the guys who are can't compete with my car. Thank you granatelli motor sports I even got an STP sticker.

No one ever quoted 15hp for Granatelli Near 0hm Wires.Not Granatelli and not J.R himself.I think this poster is thinking of up to 15% MPG. NOT HP.Anyway, best wires you can buy hands down. Nothing compares anywhere to what these can do. Tested myself with my DMM. These wires are the real deal.Thanks Granatelli. I will only use your wires from now on.

I needed a set of custom length plug wires in a reasonable timeframe, after competitors told me 3-4 weeks to make the wires, I called Granatelli and was able to place a order with JoJo trouble free... would highly recommend this company.

Just received my 1G suspension kit. Installation was a breeze. The kit is very well made. Looks great on my Gen 5 2013 SS Camaro.

I just put on your spark plug wires and new E3.54 spark plugs you wouldn't think it would make a difference but the minute I cracked the throttle I felt the difference it's true you get what you pay for .
