Car runs 10 times better than before and the thing is more responsive than it was before I would highly Recommend the coils and other parts for your car regardless if it is a daily drive car or a race car cause it makes it run smoother than OEM parts and makes it run more efficiently than before so I will buy things in the future if I need them and you guys didn't have to give me a spare set with a spare set of sparkplugs but thank you for it and I am very happy with my purchase also this was a ...

This is a great product, so far it has worked very well! Just a simple notice, this is likely to trigger your check engine light, but dont let this worry you. The code should be P0128 for coolant thermostat, the stock ECU (on my 2023 Charger R/T atleast) is programmed to reach 203°F coolant temp, the 180° thermostat doesn't get the engine up to those temps, and the computer will think the thermostat is stuck open. It is not, if you want to ensure you dont get the light for that again, a tune wil...

My Hemi has 81k milles on it and it was time to replace the spark plugs all went well but then about 4 months after changing to iridium spark plugs I was experiencing slight engine shake/stumbling only in drive while at stop lights. It wasn't throwing misfire codes in the engine computer so couldn't figure out what was the cause. Changed the PVC valve and the PCT valve and cleaned the throttle body and tried fuel cleaning additive with premium gas but none of that fixed it. As a last resort befo...

I saw some YouTube videos about these coils and was a bit suspicious but thought I might as well try them out. I am beyond happy with the performance of these ignition coils. I have a 2018 Tacoma TRD Sport with 80,000 miles and was getting about 290 miles per tank and now I’m getting 350-360. Not to mention the power difference is unreal and the 2018 tacomas have this kind of jerky shifting from the factory and since I installed these, the shifting is so much smoother. I’ve been telling all my T...

I’m glad I was able to speak to someone in the technical side and to get parts and I went online and ordered what I needed and it got to me within a couple days thank you I wish that you were more spread out but I guess you know that’s your own personal parts Where they could be accessed quicker cause if it comes off and you’re stuck inside a row you’re done because the belt comes off but thank you for your speedy delivery and your advice. Have a merry Christmas and a happy new year and I love t...

I bought fuel injectors supposedly made for my jeep "2012 wrangler rubicon 3.6 jk " and I installed them and my engine was shooting fire out of the fuel injectors because they are much shorter than the OWM ones they were suppost to be drop and go injectors!!!! I have to take apart the entire engine top end again and pay another $3000 for labor to install the correct sized fuel injector and to see what damage the short ones I was promised that they would fit have caused!!! Up until now I have pro...

This is the second thermostat I installed since the original failed a few months ago. The replacement part work initially, but then developed an issue where it would not maintain a consistent temperature. I installed the RIPP thermostat and it clearly performs very well and keeps the engine operating much cooler. One of the features that convinced me to purchase the RIPP thermostat was the design opens the thermostat 1/2" vs. the smaller opening of the OEM part. I believe this is one of the rea...
