again, after going over everything during the timing chain replacement, i noticed that all the hoses on the intake were like brittle plastic and starting to crack. i ordered the boot for the throttle body but these accessory hoses (yellow) are no longer available. are most people just pulling these off and putting a filter on the resonator by the engine? just replace the hose with heater hose etc? i'm assuming the plastic part thats integrated with the air intake track just pops out? I didn't want to force it, again, fearing it would break everything. thanks
