Installing new sparkplugs on jeep compass

There is a little controversy about this. Searching the web, the best explanation I see is:

he 0.061-0.068 gap comes from the Ford OEM Service DVDs for 2003, 04 & 05, for the 4.0L Explorer, Explorer Sport-Trac, Mountaineer & Ranger, originally equipped with the Motorcraft AGSF22PM plug. Interestingly, in 2005, the Mustang started using the same 4.0L engine. In that application, the engine was equipped with the AGSF24N plug (a hotter plug). The gap on the DVD is shown as 0.052-0.056 in.

Through 2002, all 4.0L SOHC plugs, according to the Ford DVDs, are gapped at 0.052-0.056, using AGSF22PP plugs as replacement plugs.

The 4.0L SOHC is a waste spark engine, which uses slightly different plugs on the left & right banks.

Replacement plugs are usually double platinum, suffixed PP so they can be
used on both banks.

On the 2006 and later Ford DVDs, all 4.0L SOHC plugs are gapped at
0.052-0.056 in.

On the Ford OEM parts site, the AGSF22PM plug isn't listed. The replacement
plug for 2003-05 4.0L engines is the SP400, which is shown as having a gap
of 0.052-0.056 in.

The sites for Autolite, Champion and Bosch all list replacement plugs, for
those years as having a gap of 0.054 in.

Bottom line, it looks like the original plugs in the 2003-05 engines, except
for the 2005 Mustang, were gapped at 0.061-0.068 in. Replacement plugs,
regardless of manufacturer, are gapped at 0.052-0.056 (0.054), regardless of
electrode type (iron, copper, platinum, double platinum, or iridium.

I believe the factory originals are champion brand, and would have been platinum, but it should still run decent with the coppers. The only thing I can think of is they are of the wrong gap. Copper plugs do not come pre- gapped at all and need to be done by installer. The gap for your stratus, if it's a 4 cylinder is .050. Wrong gap will cause no power and shaking. Correct champion number in copper is #443, and should say that on the box/plug.

25th is the standard gap for nearly all engines

Mr Bobby I manage to find in my books few things about your model on spark plugs. I hope will help you. Depends the make you have the Gap: 1. Autolite Ap606 Platinum Gap 0.60, 2. AC DELCO Professional Platinum Gap 0.60, 3. NGK G-Power Platinum TR55-1GP Gap 0.60, 4. CHAMPION RS12 PLP6 Gap 0.60, 5. CHAMPION COPPER PLUS RS13LYC5 Gap 0.60, 6. Platinum Alloy Gap 1,1mm if your engine size is 3.1,also for 3.1 3ngine DENSO TT PLATINUM Gap 0.04 inch. select and carry on .

Chrysler Voyager seem function well on Champion spark plugs. I had the same issue and only after buying Genuine Champion Plugs, the car resonded with power

If the AC plugs worked, I would stay with the them, and use the same gap. .060 gap is a lot, especially for an old ignition system. If you keep the Champions, gap them to .045. Personally, I never had any good luck with Champion plugs. I normally use only Autolite. The new Autolite Iridium gapped at .040 should make a big improvement as compared to the Champions.

Make: CHEVROLET
Model: SILVERADO 1500
Year: 2004
Engine: V8 - 4.8L - FI - - GAS

GAP = .040"

I suggets PLATINUM sparkplug (Morotcraft, Bosch, Champion)

Hope helps (remember to rate and comment this).

the plugs you need are ac delco you can find the replacement proceedure on autozone.com vehicle repair guides

buy platinum plugs and u wont have to worry about gapping them...

The gap is .044, decimel zero four four. Does NOT matter if a plug is copper, platinum, etc... the gap is the same.
