After 2 months of pain when I bought this car (can look at my previous posts / comment history), I have happily driven my fiesta to and from work for 2 weeks now and blasting on tight roads on the weekend.

I have put 600+ miles on my car since my last post!!

Today, I finally had some free time and thought I'd do spark plugs. It had NGK, but since I'm returning this car to stock form, i went with Ford's SP-532X.

Replaced my PCV valve. Just got 3 feet worth of 3/8" tubing and used that instead of buying the factory harness. The hardest part was removing the old tubing since I did not have a heat gun. Now the car doesn't idle as rough and does not stutter on fill up.

The carpet wasn't dirty but wanted to test out a new portable cleaner, so I took the seats out to do a comprehensive clean job. Forgot to take an "after" pic but it looks about the same in the end as there weren't any stains to begin with. I also replaced the cabin filter while the seats were out, which made the job that much easier.

I also took this chance to install seat airbag bypass plugs that I made with a pair of used airbag pigtails and 2.2 ohm resisters. I previously just shoved the resisters into the connector and taped them, but this looks much neater. I hid my crappy soldering job with shrink tubing, and the multimeter showed the same amount of resistance at ~2.6 ohms.

Late post, as I did this yesterday.
Symposer delete & Whoosh PCV hose. Was going to do the DS breather hose, but I needed to cut up a perfectly fine hose, so I didn't mess with it. Plugged the acoustic tube with one blue shop towel & threw some duct tape on there. Didn't take a true "before" or "after" photo, so all you guys get are these.
My first impressions of symposer delete were that it was quieter, but the motor noise didn't change. I'll live with it for a while, and give another update a few weeks in.

Got my TunePlus E30 base map loaded onto my car, and my NGK Iridium step-colder pre-gapped plugs came in. My darned Craftsman spark plug socket was broken. I had to go buy a Duralast one for $9. :(
I downgraded from NGK Ruthenium plugs, but they had ~30k mi, and these new plugs made the car idle smooth & perform better.
Anyway, it took me 20 minutes to get the job done in the AutoZone parking lot. IMG_0126.JPEG IMG_0127.JPEG

Removed the symposer hose finally. Just stick your hand back behind the battery box and you'll feel where the hose is connected to the firewall. The connection is the same as the ones for the evap system. Just squeeze where it's ribbed and tug it off. Then you can pull the hose out of the two clamps, one up front you gotta pry out(4th pic), and one on the back of the battery tray you can just pull out (c shaped). Now just tug the hose off that 90° elbow we unclipped, plug it up with some tape and clip it back on. Done! Not sure why so many people just leave the house there, and why so many companies sell their delete kits with a hose cap instead of a plug for the elbow end or a new elbow that clips in place.

I did that. It's a point of possible failure, and not needed if you have a full intake.
I love the sounds I get when I stomp on it. Satisfying, with stock exhaust. Quiet as stock when I don't. Great for highway driving. No drone, anywhere.
When I give it the beans, I hear beans being given at any speed. It's lovely.

My thing is though - the noise on the freeway gets irritating. I drive 120mi/day for work, so I want a smooth(er) and quiet(er) cabin (I know, the fiesta is not a luxury car, I don't expect perfection). If I want to hear induction & blow-off noises, I just roll my windows down in the city.

I received a 2680r in a trade in December and have been tinkering with it since then. Haven’t truly driven it since the trade mid December. Anyways, bought a Wor fab manifold to ditch the adapter and installed it yesterday. Finally feel like it’s the way it should be. Sent over a log to dizzy last night.

Also, bought a miltek exhaust (the one with both muffler and resonator) and it’s super quiet now.

Hey everyone. I am looking for the rear passenger side. Is this the correct color for the FiST? Thanks for the help. There are a lot of references but I am not sure if this is correct.
