Motorcraft SP550

This is the exact same part that your dealer wants $15 per spark plug. Do yourself a favor get these instal them yourself and save about $300, that’s what my ford dealer wanted for my 2016 ford escape se with 60,000 miles

Perfect fit and work great

Ad was not clear. Thought I was buying 4 spark plugs for 50 dollars, not just 2. Went to Ford dealer and bought 4 of these plugs for 46 bucks. Anyway, that’s not all. Sent them back for a refund and didn’t hear anything for 14 days, no refund either. As far as I’m concerned, this is a scam. Don’t order.

I replaced the plugs in my 2018 Ford Fusion EcoBoost 2.0L Turbo with these. The previous FoMoCo part number was SP-537. Regardless of what Amazon Garage may tell you, these SP-550's are exactly what you need. Ford changed the part designation.At 40,000, the car was slow to respond and misfiring when I pressed down on the accelerator to pass (or just speed!). I even got the dreaded flashing engine icon which tells you that raw fuel is being dumped into the exhaust system and catalytic converter... and that’s a bad situation!Ford recommends changing every 100,000 miles but from now on I'm going to spend the $25 and change them every 20K to 30K because the 2.0L EcoBoost beats the crap out of plugs WAY before 100K (see photo) even when using top quality fuel.They were relatively easy to install. It took more time to get the air intake duct out of the way than anything. If you'll go to YouTube and watch a couple of videos and are at all mechanically inclined, you can handle this. If your car has 100K or more on it, replace the coil packs while you're there. Those are even easier since you have to remove them to change the plugs anyway.

After reading about Ford engines, it's clear to me that it's better to use OEM spark plugs than other brands. Ford engines should stick to original Motorcraft plugs. There are fakes out there, so beware. These are original and after 1000 miles, continue to work flawlessly.
