Mediarocker seems to lack the ability to be objective when examining anybody's opinion including his own. If he were objective he would be trying to explain why so many people on this forum have reported no problems whatsoever over long periods of time using Bosch Plus 4's in their Taurus/Sable motors, both Vulcan's and Duratec's. One of his statements is that Vulcan's just cannot stand Bosch Plus 4's yet my 96 Taurus with Vulcan power ran beautifully with the Bosch plugs for many years. And, I am not alone as others have reported the same on this site. If he cannot think logically about pressure variances under the hood of a moving car, how does anyone think he can extrapolate worthwhile information about a brand of spark plug that seems to work just fine for many on this site and other sites. The Bosch Plus 4's are a take off of the surface gap plugs used with great success by many manufacturers at least since World War II including Mercury Marine and numerous airplane engine manufacturers. Firewall forward differential pressure build up is not a theory since every manufacturer is aware of this and some even attempt to modify and/or lower it's affect by limiting or redirecting air flow through the engine compartment to minimize its' affect on performance.[/b]
You have a Duratec according to your profile. A Duratec DOES NOT EQUAL VULCAN. :rolleyes2:
I based my comment on your profile.
Also, Marine and Aircraft engines DO NOT EQUAL a Vulcan. They run different compression ratios. And on a Vulcan, they are merely a GIMMICK. they provide no increase in performance for their price. Hence, they are USELESS. YOU FAIL TO GRASP THIS ASPECT. Many people have problems with Bosch plugs in their vehicle. Not because of lack of quality, but merely because the plugs do not function optimally under their engine's specifications. Instead of suggesting someone to buy plugs that have had a MINOR success rate, and whom is NOT seeking performance, we're gonna stay away from suggesting the bullshit +4 plugs for that reason.
Extrapolate THAT.
Insulting my intelligence due to your lack of forethought further expresses your lack of consideration in the fact that a OHV Vulcan is NOT a ###### European car that can benefit from 10 dollar plugs!
Congratulations. 5 Vulcan out of 20 can run +4's. You want an award? I refuse to support a product and will advise people AGAINST buying a product if I've failed to have good performance out of it under multiple conditions. Bosch plugs ran like **** in my Jeep, my Taurus, and my Fathers Sport Trac. So I've learned to stay the hell away from them. My buddy runs them Just fine in his BMW. I got a guy running them Just fine in his Supercharged Cobalt. Does that mean it should be a recommended plug for an average user? NO.
The fact of the matter is, if someone wants SURE RELIABLE Performance without having to chance it working or not on their vehicle, the tip is to stay away from Bosch on your Taurus. At least until everyone (and I mean EVERYONE.) starts saying otherwise. Not to down JATO, or You for running Bosch. I Just fail to see the need to increase material that will maintain more heat in the engine bay (the +4's) if there is no definitive performance gain.
Not just that but your fixation on putting a intake at the firewall of a Taurus makes no god damned sense being the temperature at the firewall of a Taurus NEGATES the effect of a ram air. That 1 PSI of pressure is 1PSI of 200* air. Which means that your making ~0 PSI of ~75* air. A Taurus CAN NOT. and WILL not Benefit from this kind of setup! No matter if Mario ###### Andretti uses the god damned setup! I understand the issue of having to redirect flow out of the engine bay. I've understood this since day one. However the firewall will never produce enough pressure to benefit the engine's induction in the Taurus.
If I still had my Taurus I'd go out right now and fit those +4's and that firewall ram air JUST to see if your theory has ground. Being I ran a HAI and actually LOST power, and running Bosch Double plats I misfired worse than my buddy's Vauxhall Corsa. I'd do it, and dyno it chancing grenading my engine just to prove to you that none of these euro mods would benefit this vehicle.
You're logic is lacking.
