Personally I wouldn’t use a washable air filter on an EFI engine. Even if I was as careful as possible with re-oiling it, I would get too much oil on it and foul my MAF sensor. I use a K&N filter on my carbureted motorcycle though.
Washable K&N gauze type filters were designed for off-road racing. Their main benefit is they do not plug up completely solid like a paper filter will do. However their negatives include letting a lot more dirt past than a paper filter as well as flowing less air when clean. Multiple engineering test have been done on this point by multiple reputable automotive magazines, I am sure you can find the test results. Unless you are racing the Baja 1000 or the Mint 400 I would never run one and I did run one for a few years on one of my street cars. The amount of sand in the intake tube is what changed my mind. When I used to race off-road motorcycles the factory uses oiled foam filters and those are excellent for off-road use, but that is a different animal than cotton gauze cone filters.

Agreed. I had a similar experience running a k&n style filter on a truck for a few years. When I ended up pulling the intake off I found dirt packed in the crevices around the throttle body where it had come thru and gotten caught on the lip. I'd not be likely to ever run one again.

ITG offers a foam filter for the D2, their WB-430.
You should replace your air box with a KN cone filter, then you could use colored silicon hose for your intake. Plus, it sounds better. in my opinion. There are always pros and cons and opinions on washable filters, I suppose it depends on how you think you would use it.
I like the idea of the silicone hose for the airbox, thank you, I didn't even think about that!
This week has been frustratingly unproductive. Lot of flooding and power outages for no reason.
Today I got the cluster and HVAC reinstalled after installing blue led bulbs as well as the clock.
Most important, got the new bearings into the idler pulleys (thanks to a post in this forum)
I swear I had ordered 2 crucifix seals but only ordered one!
Today I swapped my right front wheel and tire because the rim is bent; guess it's time to save up and upgrade. Also, I upgraded the dash lights to let's and changed them to light blue like I did the air con display.
Today was all about the items I have been avoiding haha.
To do the crucifix seals, starter comes out, but my lovely predecessor chewed up the top Allen. Got it out finally.
Next I saw that the transfer case plate bolts were round circles. Add in the blue locktite, getting all of them off was also a long ordeal.
But I won!
Front and rear diff drained and filled
Transfer case drained, plate cleaned resealed and drying
Starter out
2 side crucifix bolt out
Also installed the 2 pulleys with the new bearings and installed belt
Began bending and flaring right front brake line, it is fused with the new brake hose but luckily it's the last hose!
Also got this kit the kids wanted to try, but the seams in the disco dash don't really allow for it, but I had already cut it, so couldn't return. Put it in the poor Honda 🤣
Next I need to vacuum fill coolant while fan out so I can see any leaks
Fill power steering system
Fill transmission
