I have to thank the original poster for this thread. Quite informative and well done.

I had to do this to my Accent and love the added performance it provided on highway roll one and WOT pulls.

I modified a brake line and pressed it into the drilled hole for a factory look and even went so far as to shave the 2 plate screws for better flow at the top end.
Should do well once I do the VT engine swap and something I won't have to buy again. 😎

Here is the one I got from EBay brand new for $60.
"Brand new Throttle Body 351002E000 For 2015 Hyundai Elantra GT 2.0L 1999CC"

Great mod and should have come with this from the factory.

Instead of drilling it could you just use the tb spacer that has 3 ports built in?

Exactly what I was thinking. I watched someone on YouTube port the hose this way with an Elantra TB swap and even commented back and forth with him about it. He didn't mention any failure and everything worked fine in the video.

I was going to just have my original bored out, but it's cheaper for the used Elantra TB and the spacer from Sxth element.
I don't know if spacers produce a lot on this platform, but I assume more plenum space is better than less and it serves a purpose with the port. I'll be doing this to my car in a month or so and I'll report back.

So I did the Elantra tb swap. Just finished up a few minutes ago. I bought the spacer from KDM Tuners and it came with three vacuum ports, the correct vacuum Barb for our car is provided along with plugs for the other two holes.

I did run into the issue of fitment because of the spacer though. The mount points are rubber though, so my dad and I basically used force to make everything fit... YOLO.

Also wrapped it in DEI gold reflecta tape because it was a convenient time.

Everything else was exactly as Tuns did it without the drilling. I can upload better pics later if needed.

Looks good and the water bypass looks good as well.
Give us some feed back on how the car does now with the bigger throttle body.
👍

Thank you sir. So far after 15 miles home the car feels great. Exhaust sound is somewhat different, but it's hard to tell. Power feels smooth off the line and maybe even throughout the power band, but I couldn't really do much because of traffic. I really can feel the difference and I kind of thought it would be one of those mods that people think they're feeling a difference, but aren't. It was a pleasant surprise. $45 for the throttle body (Ebay) shipped and 70 for the throttle body (KDM) with 9 dollar priority mail charge.

Once you start getting on the throttle you'll really notice a more efficient acceleration.
Highway speed roll on's are easier and at wide open throttle to redline you'll really feel the hydraulic valve/ cam actuation come into effect. It reminds me of V-Tec from the Honda's I've driven and with the 60mm tb it really comes on stronger.

You might even see an increase in mpg's if you can stay out of the throttle. 😂😉
Good luck with it and enjoy. 🙏🏽👍
