Tech Q and A
I own a 2008 Dodge Charger SRT8® that sits in storage as long as six months without being operated. Do you recommend fogging the engine? What is the procedure to disable the engine so that I may crank it over without it starting? Do you have any winterization recommendations for long-term storage of my Charger?
MM: You can pull the ASD relay, that will keep it from firing the coils while cranking. You’ll also have to pull the fuel pump relay to keep from flooding the engine while cranking. About fogging the engine, we don’t believe it’s necessary; however, some people do like to do this for winter storage.
I’m in the process of purchasing a 2012 Dodge Charger SRT8. Is there a Mopar Cat-Back exhaust and/or cold-air intake available for the 6.4L? If so, what are the part numbers?
MM: Congratulations, that is a very nice car. We currently have a Mopar Cold Air Intake (P/N 77070043) and are working on the cat-back exhaust system. The exhaust system should be available by November.
I have 2,000 miles on my 2011 Dodge Challenger SRT8 392 and I recently smoked the clutch. During normal driving I still smell a burning odor; however, the vehicle still shifts fine. Do I need a new clutch?
MM: It’s difficult to say without inspecting the vehicle. If the smell hasn’t gone away a couple days after the incident, the vehicle may need to have the clutch replaced. We recommend taking the vehicle to your Dodge dealer for inspection.
I have a 2005 Dodge SRT4® and I believe a front wheel bearing is failing. Is Mopar Performance part, P/N P5007314, a heavier duty part than the original SRT® hub/bearing? What front hub/bearing do you recommend for my SRT4?
MM: No, P/N P5007314 is a 1995–1999 Dodge Neon ACR hub and bearing kit. The Dodge SRT4s are factory built with a different heavy-duty part. We recommend replacing it with the O.E. replacement hub/bearing, P/N 4670292AF.
I own a stock 2006 Chrysler 300C with 5.7L and I’m considering installing a Mopar Cat-Back exhaust system. How much horsepower could the engine gain with this system? Please mention any benefits and drawbacks to this system. Do you recommend any other Mopar parts to increase horsepower?
MM: Mopar Performance has a couple cat-back exhaust systems for your vehicle—both share the same performance gains, right around 12-15 hp. P/N P4510855 (shown) is the lower cost exhaust system, made of stainless steel. P/N P5155716 is also made from stainless steel but carries RSC technology which cuts down on drone noise, especially when the vehicle kicks down into four-cylinder mode. Both systems carry a lifetime warranty through the supplier. For your vehicle we carry a few other parts, such as Mopar Cold Air Intake P/N 77060003AC, and a header package P/N P5155282AB.
I am putting together an instrument cluster for my car and I have been looking at Mopar electrical gauges. The short-sweep gauges are considerably less expensive per gauge for both the water temp and oil pressure gauges versus the full-sweep of the same size. Are the full-sweep gauges worth the higher price or should I go with the short-sweep gauges and save money?
MM: It really depends on what your preference is. We feel the full-sweep gauges are easier to read. Auto Meter makes both styles of gauges for Mopar so the quality and durability are the same.
I own a 2003 Dodge Viper and I’m interested in a Mopar remanufactured engine controller (R4854704AD). I’m also interested in part durability. Could this remanufactured controller last as long, or longer, than the original factory part?
MM: Mopar remanufactured controllers are built with the same quality parts and procedures as the O.E. parts. So the answer is yes, the reman controller could last as long or longer than the original part.
