2016-2018 Hyundai Elantra AD O2 Lambda Oxygen Sensor 3921002640

Great upgrade for my Ford! Sync 3.4 works perfectly with Android Auto. Install was straightforward but needed Forscan to program steering wheel controls. Seller was responsive with programming help. Much better than the old system, worth the effort!

Installed this cam kit in my LS and it's been running strong! Quality parts, no issues with fitment or performance. Nice lope at idle but not too aggressive. Installation was straightforward with basic tools. Worth the money for the power gains, would buy again!

Finally found a quality replacement for my Soul! Fit perfectly, no leaks or issues after installation. Gaskets sealed tight, no check engine lights so far. Much better construction than previous ones I tried. Easy install for a DIYer. Highly recommend this setup!

Perfect little upgrade for my Honda! Easy to apply and looks great. Gives the front end a sportier look. Quality seems good, adhesive sticks well. Small detail but makes a big difference. Got lots of compliments already!

This RS-style grill completely transformed the look of my A4! Fitment was perfect, installation took about an hour. Gloss black finish looks premium and matches the car perfectly. Way better than the stock grill, gives it a much more aggressive stance. Highly recommend!

Installed this big bore kit on my CRF110 and it runs like new! Great power boost, easy to install with basic tools. Gaskets sealed perfectly, no leaks. Only note - had to reuse some hardware from the old cylinder. Overall excellent quality for the price, highly recommend!

Great wind deflectors for my Road Glide! Came fully assembled with all hardware, easy to install. They stay firmly in place and don't flap like cheaper ones. Quality feels just like OEM but much more affordable. Really helps reduce wind buffeting on long rides!

Love these wing mirrors! Gives my bike a unique look and they're fully adjustable. Installation was a breeze - just swapped out the old bolts. They do vibrate a bit at high RPM but still show traffic clearly enough. Great value for the price, would buy again!

Works perfectly to disable AFM on my truck! Easy to install and no more annoying cylinder deactivation. Only issue was the packaging - arrived slightly torn like someone peeked inside. Hope the seller can improve shipping protection. But the device itself is solid, highly recommend!

It's been two months and 3,000 miles, including a road trip. The grille has not rattled, sagged, or shown any signs of wear. The transformation is monumental. It erases years from the car's design and gives it a focused, aggressive posture. For the price, the quality and fit exceeded my expectations. If you have basic tools, patience, and a Saturday afternoon, this is a profoundly rewarding upgrade.

My favorite upgrade so far.

Works great to silence those annoying seatbelt alarms! Easy to install - just push them in and they stay put. Fits perfectly in my car. Super affordable solution for a common problem. Highly recommend these little clips!

Perfect fit for my Tundra! This catalytic converter came with all necessary hardware including new nuts and bolts, unlike some other brands. Installation was straightforward and it's been performing flawlessly for months. Great value and reliable performance.

Installed this RS emblem on my Camaro's grille – it instantly transformed the front end! Great quality adhesive, looks factory-made. Very satisfied with this subtle yet effective upgrade.

Perfect upgrade for my Audi! The honeycomb grill looks incredibly sleek and the build quality is solid. It was easy to install and completely transformed the front end of my car. Highly recommend this mod.
