The snorkel isn't a cheap modification but it's one of my favorite. The VX get way more attention now that I have the snorkel mounted... I get a new compliment almost everyday.
Here's the final price breakdown for this setup:
Snorkel+Shipping: $430.00
Apollo Sealed Air Intake: $100.00 * Thanks for the tip Jo
3" hole saw: $15
Weather Stripping: $5
Silicone/glue: $10
Total: $560 ...and about 6 hrs of your time.
Tools required:
Drill & drill bits
Heat Gun
Hole Saw
Metric Wrenches & Sockets
For water crossings, consider water proofing the fuse box & wire connections with silicone & electrical moisture seals. A spare alternator would also be smart.
