#85 of 102 Re: P71 cop car spark plugs [martykyj] by Mr_Shiftright HOST Nov 28, 2008 (4:55 pm)
Replying to: martykyj (Nov 27, 2008 7:05 pm) The info came right out of Alldata, which mechanics use but when I look at the Motorcraft site, that number has been superceded.   Motorcraft shows a variety of plugs for that engine actually, depending on what type you want and also depending on something called a "W engine code" which I don't know about. For that code they list a very similar number to the one from Alldata---AGSF32PM   SP493 seems to be a platinum plug for the Non W code engines.   Ford changes their plug numbers so often that by the time he reads this, there will be a new #   Replies to this message: martykyj (Nov 30, 2008 8:47 am)

My 01 MGM started missing at 94K miles and I installed the Bosch double platinum plugs I bought at Walmart. That was 22K miles ago and it has been running great ever since then.

My local dealer has an '08 CV with the commercial pkg. for sale. It's a bare bones car but seems to have all the essentials, which is all I need. Has the heavy duty package which inludes HD shocks, suspension (springs?), stabilizer bar, etc. Has the 2.73 rear axle & conventional engine. Anybody with any experience with one of these have an opinion? Thanks.   Cal Replies to this message: euphonium (Dec 01, 2008 10:44 am) calpete (Jan 07, 2009 7:04 am) euphonium (Jan 07, 2009 11:57 am) and 2 more...

Replying to: Mr_Shiftright (Nov 28, 2008 4:55 pm) The 8th digit on the VIN designates the engine code. If it's a "F" them the motor is a 5.0L OHV V8 if it's a "W" then it's a 4.6L OHC V8. I can only repeat what the dealer told me. My 4.6 L engine takes the SP493 spark plug. The local auto parts store checked their computer for AGSF-32P and it cross referenced it to the SP493. The difference between the plugs has something to do with a full thread vs. a half thread. I didn't get into it with the dealer about the thread size. To add more to the confusion, my owners manual lists AWSF32P. That's why I stick to what the Ford dealer told me. If the person that has the cop car wants to know what plug to use, I recommend he contact the Ford dealership and go from there.

Replying to: calpete (Nov 29, 2008 8:06 am) The specs indicate a car that will corner like a locomotive while feeling tiny bumps & crack lines in the road. It will be slower on the take off, but higher in the gas mileage. Keep it out of mountainous territory.

Replying to: calpete (Nov 29, 2008 8:06 am) sounds like your basic NY taxicab. I'd sit on a pillow if I were you, and don't expect to win any drag races.   On the positive side, might be a comfy enough smooth-road, straight-line, long distance commuter.

Replying to: Mr_Shiftright (Dec 01, 2008 11:07 am) Is 2.73 the standard CV/GM ratio? Am interested in good economy, not speed. Thanks.   Cal
#92 of 102 Opinion of commercial package CV by ronslakie1 Dec 19, 2008 (4:18 pm)
The 2.73 the standard ratio on the CV/GM unless you get the HPP (Handling and Performance Package). I have a 2001 GM LS with the 2.73 and it is plenty adequate. The only other mod I have is a K&N air filter, which has been on for 115K miles and I routinely get 27-29 MPG on the highway. It has been a wonderful car and amazingly still has the original battery, which will be 8 years old next March.

Replying to: ronslakie1 (Dec 19, 2008 4:18 pm) What is the method you use to check the miles per gallon you are getting? Replies to this message: euphonium (Dec 26, 2008 9:30 am)

I have used both the trip computer and actual gas used at fill-up. I have found the car trip computer to be quite accurate. In town driving is in the 17-20 MPG range.
