Kevin and Group, Funny you should bring up the intresting conversation about spark plugs for the De Lorean. I just got my Bosch shipment into day with all 5 different heat ranges for plugs. HR6DC for the purest, HR7DC little hotter, HR8DCX,HR9DC,and HR10DCX the hottest, all of these are $2.50ea and will be on the web site soon. I'm glad to see someone experminting with Plat +4 as Robert did. I talked to Bosch tech department about the plat + 4 and the De Lorean he said that Bosch makes no claims to anything about performance, but he said it's like beauty, it's in the eyes of the beholder. As a jobber for Bosch I will have a price on them tomorrow and it will be about 1/2 of what stores are.The info will be on the web site in about a week. New catalog info and specifications to are comming and I will put that on the site also. I also agree with David about quick bolt on performance cheap solutions, but,but,but 4 tip spark plugs have been around for years and a lot of people including me believe in them. If they didn't have some value to them, then why would Bosch build them. Even though there is 1000's of volts going to the tip of the plug, electricity follows the least line of resistance. Couple that with a new coil and Robert may even see a better performance or more stable performance. I to would like to see better performance from the car w/o spending $1000.00's. Gene Snow a race car driver told me years ago that for the money, an exhaust system got more HP for the dollars. Grant you, this was in the 70's. Showing my age.
